Hall of Fame Dolphin Buoniconti to donate brain to CTE research

Hall of Fame Miami Dolphins linebacker Nick Buoniconti has announced that he intends to donate his brain to concussion research.

A member of the 1972 Dolphins team that went undefeated, the now 76-year-old has suffered from cognitive issues in recent years.

"This is not easy, it's difficult. I'm not half the man I used to be," Buoniconti said, according to ESPN. "I don't do this for myself. I do it for the thousands of others who will follow me."

Buoniconti played for 14 seasons, during which he made six AFL All-Star Games and two Pro Bowls. After his death, his brain will be donated to Boston University's CTE research program.
