MONTREAL - One of the most storied careers in mixed martial arts has come to a close. According to UFC President Dana White, longtime UFC fighter Chuck Liddell, who suffered a first-round TKO loss to Mauricio "Shogun" Rua in the co-main event of Saturday's UFC 97 event, is retired from fighting. "He's a huge superstar, and we could still sell lots of tickets (with Liddell)," White said.
