Hall of Fame defensive lineman Warren Sapp wrote Tuesday on the Players' Tribune he plans to donate his brain to science in order to aid research into chronic traumatic encephalopathy (CTE).
Sapp, who played 13 years in the NFL, said the fact he's beginning to suffer from cognitive issues helped him make the decision:
"I've also started to feel the effects of the hits that I took in my career. My memory ain't what it used to be. And yeah, it's scary to think that my brain could be deteriorating, and that maybe things like forgetting a grocery list, or how to get to a friend's house I've been to a thousand times are just the tip of the iceberg.
