MOORESVILLE, N.C. — Dale Earnhardt Jr. is calling his decision to donate his brain to science a “no-brainer,” according to the Associated Press.

The NASCAR driver has pledged to donate his brain for concussion research when he dies, according to SB Nation.

Earnhardt made the announcement on Twitter when retweeting a Sports Illustrated article about three Oakland Raiders players who plan to donate their brains for Chronic Traumatic Encephalopathy research.

George Atkinson, George Buehler and Art Thoms said they will donate their brains as a tribute to the late Ken Stabler, who died last year from colon cancer. After his death, doctors discovered Stabler was suffering from Stage 3 CTE, according to Sports Illustrated.

Earnhardt is no stranger to head injuries. He suffered a concussion during a May 2002 race and then suffered two more within a six-week period in 2012.

The NASCAR driver self-diagnosed the concussion he suffered at the Kansas Speedway in 2012 and did not seek any further medical evaluations after he was cleared at the track. He did, however, go in for further evaluation several days after a crash at the Talladega Superspeedway that same year.

Since Earnhardt revealed that he did not disclose that he had a concussion on two occasions, NASCAR has revised its policy for dealing with head injuries.

All drivers are now required to undergo preseason baseline neurocognitive testing, according to SB Nation.
