MONTREAL — Fifty-one-year-old Herschel Walker may not have seen his last action in the cage just yet. After competing twice in Strikeforce, Walker has been inactive from mixed martial arts for over two years, but recently said in a radio interview that he would like to fight one more time, under the UFC banner. I would love to do it again, he said on The Lavar Arrington Show with Chad Dukes. I absolutely love MMA. I think it’s an excellent sport.Since the UFC acquired Strikeforce, Walker has gone unmentioned for a possible date in the octagon. Maybe that’s because most figured Walker had no prayer of fighting under White, who once slammed the signing of Walker to Strikeforce as ridiculous and completely disrespectful to the sport.Well, perhaps Walker’s two forays — both TKO wins — converted him, because White wouldn’t rule out the possibility when it was broached after the UFC 158 press conference.I don’t know, he said. I’ll have to talk to him.White noted that at his age, Walker would have to be approved by an athletic commission before competing. The former NFL and collegiate star is a well-known physical marvel, who claims to keep fit by doing thousands of pushups and sit-ups every day. White trained at the San Jose, California based American Kickboxing Academy for his two previous bouts. If Walker were to get a fight this year, he would tie Ron Van Clief as the oldest man ever to compete under the UFC banner. Van Clief was also 51 when he lost by submission to Royce Gracie at UFC 4 back in 1994.I’ve never even thought about it, but I’m assuming he’s under contract with us from the Strikeforce deal, so I don’t know, White said.
