For past couple of years, former NFL running back Herschel Walker has been steadily training in the mixed martial arts world. He's currently 1-0 in his short MMA career and is gearing up for his next fight on January 29 in the Strikeforce MMA league. But in a press conference to promote the fight, Walker told reporters that he's considering an NFL comeback.

"I know I can play," Walker. "If I continue to stay in the shape I'm in now, I know I can play when I'm 50. Right now, if you asked if I can play today, there's absolutely no doubt in my mind I can play football today, that I can help out a team today. I 100 percent guarantee you I can help a football team out."

He also said that he's in better shape than he was in his 20s and last year when the 40-yard dash in 4.38 seconds, a stat that NFL coaches salivate over. Walker played for Dallas, Minnesota, Philly, and the New York Giants through his 12-year career before retiring in 1997. He was selected to the Pro Bowl twice in his career and ranked eighth in all-purpose yards with 18,168.


"I still say I may try out for football again and show people I can do that, because I want to be the George Foreman of football and come back and do it one more time," he said.
