Herschel Walker says he could still play in the NFL at 52.
Now Walker says he could still be a contributor, telling the USA Today, "I couldn't take every snap. But running backs nowadays don't play every down."
"Now they send in the choir section. Physically, I can still do it."
The 1982 Heisman Trophy winner has been training as a mixed martial artist, and although he isn't planning a comeback, I'm sure that if he got a call he would consider trying out training camp.
Walker spent 12 season in the NFL with the Cowboys, Vikings, Eagles, and Giants.
