Dale Earnhardt Jr. plans to donate his brain for research on concussions, he tweeted on Saturday.
The 41-year-old made the statement while responding to a fan that said the plan of three former Oakland Raiders players to donate their brains “sounds like a big commitment.”
Earnhardt had retweeted a story from Sports Illustrated early in the day about the former Raiders.
He went on to say that he plans to donate all of his organs in some fashion.
Earnhardt is the latest athlete to pledge their brain for science, joining a list of football and soccer players. Most recently, U.S. Soccer Hall of Famer Len Oliver said that he will donate his brain for CTE research.
