NASCAR champion Dale Earnhardt Jr. will donate his brain for concussion research after he dies, he said on Twitter.

The 41-year-old race car driver from North Carolina said Saturday that he would make the contribution to science after retweeting a Sports Illustrated story about three former Raiders committing to the same research on chronic traumatic encephalopathy (CTE). The athlete was responding to a commenter who said “sounds like a big commitment.” “Why? What use is it to you at that point? I’m gonna donate mine,” Earnhardt Jr wrote.

He also said he would give away his organs. “I’m donating everything one way or another,” he tweeted.

Retired soccer star Brandi Chastain has also pledged to donate her brain to concussion research.
