Rice, who retired last July, estimated that he sustained eight to 10 concussions during his football career, the first of which he believes occurred when he was a child. Weatherford said he thinks he has sustained two concussions while in the NFL.
Weatherford said he's doing it "more to help generations after us."
"You study [Rice's] brain, by comparison to my brain. 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. For me, it's about overall health right now, but you want to help the future and pay it forward," he said.
