"If I continue to stay in the shape I'm in now, I know I can play when I'm 50," Walker insisted yesterday during a teleconference to promote his Saturday bout with 27-year-old Scott Carson in a Strikeforce event in San Jose, Calif.
"Right now, if you asked me if I can play today, there's absolutely no doubt in my mind I can play football, that I can help a team out," said Walker, whose spent his final three NFL seasons primarily as a receiver and kick returner for the Giants and Cowboys. "I can 100 percent guarantee you I can help a football team out . . .
"I think I'm a better conditioned athlete right now than I was when I was playing. I'm 48 now, and I'm in better shape now than I was in my early 20s playing football."
A remarkably versatile athlete who flashed Olympic-level sprinter's speed for the Georgia track team and made it to the 1992 Winter Olympics as a bobsledder, Walker's latest - or, more accurately, most enduring - competitive passion is mixed martial arts. A student of MMA since he was 15, he holds a fifth-degree black belt in tae kwon do and also has trained in such varied fighting disciplines as Muay Thai and Kenpo.
The matchup with Carson (4-1), originally scheduled for Dec. 4 but postponed when Walker (1-0) was cut above his eye in training, is the second with Strikeforce for the 1999 College Football Hall of Fame inductee. He made his debut by scoring a third-round technical knockout over another opponent more than 20 years his junior, Greg Nagy, on Jan. 30, 2010.
