Harvard to lead $100m study of NFL players

Cross-campus research on 1,000 retired players aims to treat, prevent wide health problems

The National Football League players union, alarmed that its members die nearly 20 years earlier on average than other American men, has selected Harvard University to oversee a $100 million accelerated research initiative aimed at treating and ultimately preventing the broad-ranging health problems plaguing the athletes.

Legions of Harvard specialists from across its many schools and affiliated hospitals will team up with the NFL Players Association in an unprecedented study of 1,000 retired players. The researchers will look at everything from their repetitive brain traumas, torn knee ligaments, and arthritic joints to the gnawing effects of long-term exposure to acute pain and chronic use of painkillers.


The 10-year collaboration carries an ambitious goal: ­begin to transform the health of active and retired players within five years.

The stakes are high — for the players and for the NFL.

More than 100 concussion-related lawsuits have been filed against the league, with thousands of players claiming the NFL did not do enough to inform them of the long-term dangers from repeat brain injuries and protect them.

Public attention has focused on an Alzheimer’s-like condition, called chronic traumatic encephalopathy, that is thought to be caused by repeated blows to the head. It has been linked to the erratic behavior, depression, and deaths of several former players, including Junior Seau, a linebacker for the New England Patriots and other teams who committed suicide in May.

But the health problems are much wider-ranging. Countless former players struggle with searing and debilitating joint pain and rely heavily on anti-inflammatory medications and painkillers, say union officials. Many others grapple with heart disorders linked to extreme strength training common in the NFL.

The result is a dramatically shortened life span: While white men in the United States on average live to age 78 and African-American men to about 70, “it appears that professional football players in both the United States and Canada have life expectancies in the mid- to late-50s,” Harvard researchers wrote in a summary of their project.


Domonique Foxworth, the 29-year-old players association president, understands chronic pain. A torn knee ligament ended his career prematurely, forcing the cornerback to retire last year from the Baltimore Ravens. “There is a constant discomfort in my knee and hip,” he said in an interview.

“You get used to it,” he added. “I hope this project gets us to a place where players some day don’t have to get used to it.”

Foxworth said there hasn’t been a concerted effort to understand “how this game affects our players in the long run.”

Frustrated by the inattention, the union opted to give up some salary in the 10-year collective bargaining agreement signed with the NFL in 2011 and earmark the money, $11 million annually, for medical research.

Last July, it sought applications from top research centers. Roughly two dozen applied, including Boston University School of Medicine, which has led the research on chronic traumatic encephalopathy and received $1 million for the research from the NFL. The finalists were the University of Michigan, Duke University’s Health System, and Harvard.

Harvard’s winning proposal involves an unusual degree of cooperation among the university’s many parts, tapping expertise from across its 10 schools and 16 academic medical centers. It also draws on about 20 research centers nationally that specialize in minority health issues.

“In order to make real breakthroughs in the complexity of today’s medicine, you need to create teams,” said Dr. Lee Nadler, director of the football project and dean for Clinical and Translational Research at Harvard Medical School. “We have created teams and that’s not natural at Harvard.”


The project builds on a major National Institutes of Health grant Harvard received in 2008 to hasten the time it takes to bring ideas from the laboratory to the public, and the new undertaking is the most extensive collaboration the university has attempted. Nadler, however, said the aggressive timetable was not too ambitious: “Remember, this is Harvard,” he quipped.

Nadler said the Harvard team, with help from NFL players, will recruit a geographically, racially, and ethnically diverse pool of 1,000 retired players to be screened with blood and other health tests and questionnaires.

From that pool, the scientists will select 100 of the healthiest and 100 of the least healthy to undergo extensive tests of brain function, physical abilities, cardiovascular health, and cellular changes to construct a “biological profile” that will identify specific disease patterns. They will also examine lifestyle and even regional differences in diet to identify factors that contribute to players’ risk for severe health problems.

“Dietary, and even training-related issues, like training in the heat, need to be incorporated into our assessment,” said Dr. Ross Zafonte, the program’s co-director and vice president of medical affairs at Spaulding Rehabilitation Center.

The scientists will then test therapies in retirees who have biological profiles similar to those of the sickest players, to see whether they can forestall serious problems. The treatments might include specialized diets, medications, or exercise regimens.


“We are not trying to change the game,” Nadler said, “We are trying to change the impact of the game.”

He said researchers have already identified “shovel-ready” experimental treatments that are ready to be tested in players, including one that aims to regenerate torn anterior cruciate ligaments. He said research in sheep has shown promise, but it has not yet been tried in humans.

Roughly 42 NFL players tear this critical knee ligament each year, increasing their risk of debilitating joint disease, and current ACL surgery often is not successful, as Foxworth found out.

Also ready for testing is the use of light emitting diodes, better known as LEDs, to treat concussions, in hopes of preventing permanent brain damage. Harvard researchers have reported improved cognitive function is some concussion patients who received this treatment. Also planned is a clinical trial testing whether reductions in strength training after players leave the game will reduce heart problems.

Armed with the biological profiles of specific disease patterns, the researchers also aim to identify 100 college football players headed for the NFL, and another 100 just beginning their college careers, to see whether they can pinpoint in these apparently health players the markers of disease found in the very ill retired players and test intervention therapies.

“Our organization is a role model,” said Foxworth, the NFL players union president. “It’s exciting to believe that whatever improvements we find will trickle down to them.”


One of the many other goals of the project is to focus on the unique mental health problems and needs of players who become millionaires by age 24 and are out of the league with career-ending injuries soon after.

“Players are not all that aggressive with sharing the details about something as fragile as mental health,” Foxworth said. “We are going to try to figure out the best possible way of communicating with our players, to find the best ways to get our players to open up because we find out about it when it’s far too late.”

The players union is still finalizing details of the project with the NFL, because the money set aside for medical research under the collective bargaining agreement is to be jointly administered. But the union said it plans to announce the Harvard-led project at a Thursday news conference in New Orleans, where the Super Bowl will be played Sunday.

The NFL said in a statement that it has “no higher priority than player health and safety at all levels of the game.” It said NFL officials look forward to “learning more about the Harvard study and hope that it will play an important role in advancing medical science.”
