The NFL Players Association is asking the NFL to stop a new study showing that players are “at a greater risk for the development of chronic pain” in retirement than in the same position a decade earlier.
In a letter to NFL Commissioner Roger Goodell, the Players Association (PA) asks the league to cease the study.
The letter is a direct response to a September 11, 2018 memo from the National Institute of Neurological Disorders and Stroke (NINDS), which cited the NINDS report.
The NINds study was a study of players from 2001 to 2010.
It found that the rate of chronic injuries in players from a variety of positions was much higher than in those who had retired.
The PA says the new study has no “evidence to support the association between the number of years in NFL football and the development and progression of chronic diseases.”
The NFLPA says the study was designed to identify “the number of long-term NFL players who are at risk for developing chronic diseases over time.”
The league has not responded to a request for comment on the letter.
The NINSD memo cited an article published in The Lancet in February 2018 that said players in the NFL have “significantly higher risk of developing a variety or chronic diseases,” including chronic pain.NINSS found that “the rate of lifetime NFL players sustaining a concussion was 30 percent higher than the rate in non-playing counterparts.”
The NINS reports did not give an estimate of the risk.
The National Football League and the NINS have not commented on the PA letter.
The league did not immediately respond to a question about whether it has any plans to change the study methodology.
