Does MLB Have a Concussion Lawsuit in Its Future?

The new baseball season is upon us. But even before the Cubs and Marlins began play today, indications from this spring have suggested that a dangerous trend, apparent last year, has continued into the present one — namely, an increased incidence of concussions.

Before I address that, though, first a brief primer on what concussions can do to a baseball player. In 2010, first baseman Justin Morneau was running a 183 wRC+ and had established himself as one of the best hitters in baseball. After suffering a concussion that knocked him out for the remainder of the season, he was never the same, failing to play a full season until 2012 or to cross the 120 wRC+ threshold against until 2014. Third baseman Corey Koskie was a borderline star before suffering a concussion with Milwaukee; he never played again. The way he describes the effects are frightening: “I remember walking up to the plate, thinking OK which way do I run again?”

Joe Mauer‘s career was derailed by a concussion that gave him blurry vision for two years; he was hitting .324 with a 143 wRC+ when he suffered the injury in 2013 and didn’t eclipse a .300 batting average, a .350 OBP, or a 110 wRC+ again until 2017. Last year, Brandon Belt’s season was put on hold by a concussion, as well; he experienced feelings of depression and lethargy.

In perhaps the most tragic case, Cincinnati utilityman extraordinaire Ryan Freel committed suicide in December 2012. Freel had suffered 10 concussions during his career and was posthumously diagnosed with Chronic Traumatic Encephalopathy. CTE is a disease caused by repeated concussions or traumatic brain injuries and which was most famously diagnosed in the late Patriots football player Aaron Hernandez. Suicide and aggression are two symptoms of CTE. There’s even research to suggest Lou Gehrig didn’t suffer from ALS, but instead had CTE.

Back in 2011, Jeff Zimmerman examined concussions in baseball for this very site, prompted by career-threatening concussions to Jason Bay and Morneau. He found 50 reported cases over the previous nine years, dating back to 2002. A couple of months later, MLB adopted a new concussion policy, which included a seven-day disabled list and neurocognitive testing. Seven years later, however, there’s some question as to how well the policy is actually working.

There’s no doubt that concussions — at least reported ones — have been steadily rising since the advent of the policy. There were nine reported concussions throughout all of major-league baseball in 2010. In 2017, eleven catchers alone suffered concussions, leading CBS Sports to dub 2017 as “The Year of the Concussed Catcher.” A 2014 study found that 12% of concussed major leaguers never returned to play (althoughthat study admitted that data was sparse and more research was required). It’s also a lot easier than you might imagine to suffer a concussion. In one study of concussions suffered by batters hit by pitches, “the average pitch velocity that resulted in a concussion was 91.6 mph (compared to 90.8 mph for pitches that did not result in a concussion upon impact), no players observed loss of consciousness and the average days missed for concussed players was 14.2.”

It could be argued that the rising rate of concussions actually represents good news, with more players reporting them and getting treatment under MLB’s policy. But a University of Rochester study in 2014, which included two years of post-policy data, concluded that MLB players “may not be fully recovered” when medically cleared to play. The Principal Investigator on the study, Dr. Jeffrey Bazarian, concluded that “[a]lthough players who sustain a concussion may be symptom-free and cleared by MLB protocol to return to play, the residual effects of concussion on the complex motor skills required for batting may still be a problem.”

In other words, the number of known concussions is on the rise, and the current methodology for treatment might leave something to be desired. Players aren’t immune even in spring training; Clint Frazier was running after a fly ball this spring when he ran headlong into a wall at the Pirates’ complex in Bradenton, Florida. He suffered a concussion from the impact. He still hasn’t recovered. “I can’t even sit in my living room without feeling like s—,” he told ESPN. “My head hurts, and it’s just the headaches. I can’t shake the headache all day.”

According to Corey Dawkins of Baseball Injury Consultants, a plurality of concussions are suffered by catchers, especially on foul tips. That’s led some catchers to eschew their newer, one-piece catchers’ masks in favor of the older two-piece design, which may better protect against concussions. Eno Sarris wrote about this in 2016.

Now, to be fair, MLB’s concussion problem isn’t anything like that on the levels seen in other sports, like the NHL or NFL. But with pitchers throwing harder than ever before, the risk of concussions to catchers on foul tips has actually never been greater, even with our increased knowledge. And that’s why MLB might have a problem — because, as we’ve seen, the data suggests that the concussion problem in MLB might not be getting better, and in fact might be getting worse.

Such developments can have consequences. Under the terms of their 2017 concussion settlement, the NFL agreed to pay hundreds of millions of dollars to current and former NFL players related to claims about concussions. Specifically,

[t]he lawsuits [against the NFL] ar[o]se from the alleged effects of mild traumatic brain injury allegedly caused by the concussive and sub-concussive impacts experienced by former NFL Football players. Plaintiffs seek to hold the NFL Parties responsible for their alleged injuries under various theories of liability, including that the NFL Parties allegedly breached a duty to NFL Football players to warn and protect them from the long-term health problems associated with concussions and that the NFL Parties allegedly concealed and misrepresented the connection between concussions and longterm chronic brain injury.

That settlement has its own slew of administrative problems, but those are irrelevant here. Suffice to say there’s a disagreement regarding who gets the money.

Nor is the NFL the only body having to contend with the issue. There have also been similar lawsuits brought against the NHL, NCAA, and youth sports, which proves that these cases aren’t going away. And so, in light of the data we have, it’s worth asking whether a similar kind of lawsuit could be brought against MLB.

Nathaniel Grow asked this question back in 2015, but since then we’ve seen a lot of developments in this area, particularly in the NHL lawsuit. So let’s start by assuming that the claims raised by MLB players would be similar to those raised in the NFL and NHL cases, which are summarized pretty nicely in the  NFL settlement and Nathaniel’s piece.

The NHL lawsuit is useful here because the arguments are pretty similar to what I imagine we’d see in an MLB case — and, if you’re counsel for MLB, it’s not good news. Nathaniel posited in his 2015 piece that were a lawsuit brought against MLB, the league could respond by moving to dismiss the case, arguing that it was barred by the applicable statute of limitations and that any legal duty owed to the players (and thus, the players’ right to sue) was governed and limited by the collective bargaining agreement. The NHL made pretty much those exact arguments, but the NHL lost its motions to dismiss — and pretty decisively, too.

In the NHL case, the court ruled that it was an issue of fact whether the statute of limitations had run, because the injury alleged was an increased risk of brain injury (like CTE) as a result of concussions and not just the brain injury itself. The court went on to find that the players had stated a plausible claim for fraudulent omission and fraudulent concealment; the league, they contended, hadn’t informed players what all of the risks of head injury were related to playing hockey. A year later, in perhaps the biggest blow, the court denied a motion to dismiss based on labor law preemption, saying it was not clear without discovery whether the CBA preempted the plaintiffs’ claims.

I won’t go into the full analysis because it would take too long, but the most relevant point is this: all of the traditional defenses — statute of limitations, CBA preemption, and assumption of the risk — failed to achieve dismissal of the case. That doesn’t mean they won’t work at a trial, but it does mean that the NHL is currently slogging through long, expensive litigation, including discovery. And last week, the court held a hearing on whether to certify the case as a class action, which would make this even longer and more expensive for the NHL, and expose the league to potentially hundreds of millions of dollars in liability. (It’s also worth noting that the CBA wouldn’t help MLB with a class action of minor leaguers for concussions, because the agreement doesn’t apply to them, and one study found 266 minor-league concussions over a two-year period.) It’s possible — even likely — that a class action against MLB would proceed similarly to the one against the NHL.

So what can MLB do? First, MLB has taken an important step in making mandatory a newer, stronger batting helmet. But with concussions still a problem after the 2011 policy, more can — and should — be done. Making a similar requirement for catchers would be a prudent move, perhaps with the helmets Eno discussed. Perhaps pitchers, too, should wear helmets to prevent episodes like this, which has also happened to Johnny Cueto and Brandon McCarthy, among others.

Given the University of Rochester study — as well as similar research, which gives a normal concussion recovery time for most people at seven to 10 days — the seven-day DL might be conservative; it might be worth bringing back the 15-day DL, just for concussions. At the very least, it’s worth having some qualified medical and neurological professionals do some research into the problem, as Bazarian told Reuters. As for whether taking those steps would be tantamount to an admission of fault by MLB, legally it probably wouldn’t be; the vast majority of jurisdictions have a variation on this Rule which says that subsequent remedial measures aren’t admissible to prove negligence or other culpable conduct.

So there’s really very little downside here and potentially a lot of upside. The average professional baseball playing career is just 5.6 years, which means there’s a lot for that player’s brain to do when it’s done timing fastballs.

Oh, the irony of denying minor league players union membership and coverage by the CBA coming back to bite MLB in the ass, would be just too delicious.

Time to get rid of catchers.

I stipulate that you, Sheryl Ring, need to write two articles on each issue. The first is as a baseball fan and a nerd, where you dive into the issue of the history and prevalence of something. The following article would regard the legal ramifications, because you’re a lawyer and you’re offering us all a wonderful cornucopia of lawyering that this site most definitely needs. I enjoy both sides, but I get confused easily when I read these articles.

Also, seriously, keep up the good work.

Funny you mention Johnny Cueto without mentioning he kicked Jason in LaRue in the head in a brawl, causing a concussion and ending his career

And about Freel and suicide, it would be helpful to compare the rate of suicide among MLB players/former players to men of the same age.

I have no skin in the game, being neither a particular fan of either guy or any of their teams, but I think that’s an exaggeration. Cueto definitely gave LaRue a bad concussion, the effects of which I hope have ended by now, though I don’t know.

More importantly, LaRue’s career was hanging by a thread before the kick. He had amassed a grand total of 0.5 WAR in 789 PA over 5 years leading up to the brawl. He was 36, offered absolutely nothing at the plate, and his defense had seemingly eroded at least some.

This is not to minimize the actions of Cueto or the medical effects it had on LaRue. But LaRue’s career was, for all intents and purposes, over after that season anyway.

Concussions are major problems in many professions. As a 20 year veteran in federal law enforcement (and recovering lawyer), I assure you my profession has resulted in many, many concussions. I have never even heard of any concussion “protocol” in my profession, so I suspect my colleagues normally return to work without much assistance, often without even knowing they suffered concussions. My father in law is in construction, and he agreed with me that his line of work results in many concussions. Firefighters, military, boxers, and I am sure a great many other professions have elevated concussion risks.

I am definitely not opposed to improving conditions for ballplayers, and I am also not opposed to class action lawsuits when appropriate. But to be fair, concussion risks are part of a number of professions, and I get the sense that the public is much more concerned about helping athletes than they are about helping people like me and my colleagues in this regard. And although I’ll get plenty of down votes, I am also correct when I say that is a shame.

The issue is that it is very difficult to prove that medical issues years or even decades later stemmed from an individual concussion.

Why don’t teams put huge super thick soft padding on all outfield walls? If I were a team owner paying outfielders millions of dollars, I’d want them to be able to hit a wall at an all out sprint and not get hurt. Are there rules prohibiting this?

Outfielders running into walls probably isn’t a major source of concussions or injuries more generally, but might as well mitigate where you can.

What is the Labour Law difference between the strength of an MLB case vs. an NFL scenario, when MLB contracts are fully guaranteed and NFL contracts are not?

That is, how much personal responsibility is there for an MLB player (or his personal doctor) to say “I’m not right”?

Aside from machismo (which can occur in any sport), NFL players faced the prospect of being terminated with nothing (or a small injury settlement) if they couldn’t play.

While the reality may be murky for the last guy on the bench (or impending free agents), at least in theory an MLb player should be able to say “Whoa, Skip, my coconut still hurts, and we need to get that sorted out properly before I can help the team again” without fear of termination.

Really skeptical a lawsuit here could overcome the assumption of risk doctrine. As an example, a catcher has most likely taken foul tips to the head in little league, high school, college, etc. long before reaching the major leagues. At that point it seems it would be an unconvincing argument that the catcher was not aware (or should not have been aware) of the risk and did not voluntarily accept the risk.

I really enjoy these articles because baseball and the law are two of my favorite things, but the answer to this is no. At least not a lawsuit that would go anywhere. I don’t think this passes the assumption of risk test (and I don’t know the exact wording of a standard employment contract at the MLB level but a clause may exist within it applying to this).

One aspect not discussed in this article is that unlike the NFL and NHL, Major League Baseball does not have strict equipment rules. Players are free to protect themselves as they see fit in terms of helmets, masks, “armor” (ie Bonds), etc.

Both the NFL and NHL have very strict requirements of how helmets, facemasks and padding are designed and to be worn, requirements up until very recently did not provide much protection. It is very easy to make the case against both of those leagues that they failed to do enough to protect their players because they very obviously didn’t and players had no means to take it into their own hands. MLB doesn’t *need* to protect their players because players are more than free to protect themselves.

If a position player wants to wear a helmet in the field, they can (as John Olerud did after suffering an aneurysm in college). If a catcher wants a custom designed helmet to provide extra protection, they can do so and have done so. If a batter wants to wear a dual flap helmet or a helmet with additional jaw and face protection, they can. If a pitcher wants to wear a padded hat, they can. It has been that way for the history of baseball and to date, very few have availed themselves of that. Part of that is the lack of corresponding science on the topic up until recently, but the bigger part is that players just don’t want to do it. It isn’t comfortable, it isn’t “cool” and in a superstition heavy sport, it would probably curse a player (in their mind). Even now when we have very clear science on the subject, players just have zero interest in doing it.

MLB has done just about everything they can to protect its players from head injury. They removed collisions at the plate, they have padded walls and have some down forcefully (but not forcefully enough) on beanballs and going back even longer, MLB started swapping out baseballs so darkened balls that were less easy to see were no longer in play. There is nothing else MLB can do. Players will never, ever, EVER approve any change to the CBA that requires helmets for pitchers or these other protections so ultimately, it is on the players to accept the responsibility. The MLB player’s union is far stronger than the unions of other professional leagues, at some point the union needs to take responsibility for the protection of its members.

All that said, MLB should be sued to hell and back for failing to protect *fans* from injury. It is unacceptable that it took until 2018 for netting to be extended.

I agree with the entire first half of this. Where you starting getting into the “MLB has done everything they can” and the “there’s nothing else they can do” is where I disagree. I’m not specifically sure *what* else can be done, the the assumption of completion in almost any instance is not a smart bet.

Regarding the choices players are given – this is overall probably the best part of their attempts though. You run into problems by mandating certain pieces of equipment. For example, mandating 1 of 2 very specific catcher helmets because it’s safer is a terrible idea. It makes inclusion of the next, safer technology that much more difficult to implement. Their place should be endorsement, not coercion.

Also, not something you mentioned, but I find the suggestion of reinstating the 15 day to be absurd. It was lowered to 7, because teams did not want to be locked into 15. With 7, they can take 10, or 15 or more if necessary. Seems silly to do otherwise.

The evidence that Lou Gehrig died of CTE is flimsy at best. No one else has rapidly declined and died directly due to CTE. His many concussions were likely a contributing factor to him developing ALS, but there is no way to know for sure.

Thank you for the article. In baseball, like in other sports the effects of concussions on performance and long term health effects are only beginning to be understood.

I think a lot more could be done to protect against concussions. For example, external padding on batting helmets would certainly provide more protection. Implementation is hard because it likely reduces performance because it would be heavier and bulkier (there’s also the coolness/ manliness factors as well). Therefore, implementing additional protection would need to be mandatory because of the resulting competive disadvantage.

Many years ago the Buffalo Bills had a player or two wear padded helmets (one was a receiver but I can’t remember his name). It was a good idea then. It is an even better idea now. I remember how much these players were mocked. It is disappointing that no team has followed up on using externally padded helmets.
