Two NFL players have announced they will donate their brains for medical research after their deaths.
New York Giants punter Steve Weatherford and former NFL receiver Sidney Rice announced their decision on Tuesday's Fox and Friends.
"Just because you (haven't) had traumatic head injuries doesn't mean you don't need your brain studied because they're going to have brains to compare to other ones," Weatherford said.
"For me, it's about overall health right now, but you want to help the future and pay it forward."
Rice, 28, estimates that he sustained eight to 10 concussions during his seven-year football career, the first of which he believes occurred when he was a child. Weatherford believes he has sustained two concussions in his nine-year career.
"This is something that has affected Sidney and affected me in the form of one of my dear friends, Junior Seau, committing suicide," Weatherford said.
Seau, a 12-time Pro Bowl linebacker, died after shooting himself in the chest in 2012 at age 43. Seau suffered from CTE - chronic traumatic encephalopathy - a type of brain damage common in people who suffered repeated head injuries.
Last summer, the NFL settled a lawsuit from more than 4,500 former players after they sued for damages regarding concussion-related health issues.
