Study finds over 24 percent of NFL players had CTE from 2016 to 2021
Summary

A new study from The BMJ reveals that at least 24.5 percent of NFL players who died between 2016 and 2021 had chronic traumatic encephalopathy (CTE). Out of 878 deceased players, 215 were confirmed to have CTE, while 643 brains were not studied, suggesting the actual percentage could be higher. The NFL and NFL Players Association acknowledge these findings as a serious reminder of the risks associated with playing football. The issue raises questions about the involvement of the Occupational Safety and Health Administration regarding player safety. Calls for action are growing as long-term health risks continue to be highlighted within the sport.
