That's according to the chicken mogul and budding mixed martial artist on yesterday's Strikeforce conference call:

"I left not only my home in Dallas but also my company. I’ve left my company to my top guy and I’ve come out here to [San Jose] to train. I moved into a hotel in July to begin training. And then the fight came along and I first asked my trainers and the fighters and they said yes you can do it. And that’s the only reason why I’m back doing it. How long can I do it? Who knows. I tell people I may even try out for football again and show people I can do that one more time. I’d be the George Foreman of football and come back and do that one more time."

While I don't know how much his skills have deteriorated, his 48-year-old physique certainly hasn't. Maybe Walker will inspire a generation of forty-somethings to switch to his meatless diet, which consists of eating soup and salad once a day. If the former NFL running back can get past Scott Carson at Strikeforce: "Diaz vs. Cyborg" on Saturday night (Jan. 29) in San Jose, does anyone want to see him take another shot at the gridiron? And having not played since his retirement in 1997, would he even make the cut?
