B.J. Penn reveals only a bad knockout or a beating would make his walk away from mixed martial arts

Former UFC lightweight champion, B.J. Penn has been speaking about the twilight years of his long and storied career and what it would take for him to hang up his gloves once and for all, explaining only a bad knockout or a bad beating would do the trick at this stage.
Speaking via HDNet Penn said:

“You know what? A lot of other fighters out there they probably would have went and picked a fight that they know they would have won and leave on a high note but that’s Randy (Couture), that’s the only way he would have gone out (getting knocked out by Lyoto Machida). I probably would kind of think for myself the same. If Randy would have won, he would be fighting for the title. He wouldn’t have left. You know, we lost so many times over the years, we all know that’s not the first time Randy got knocked out but that’s probably what’s… It’s probably going to take a knockout or a bad beating to make someone like Randy or someone like me or a couple other fighters that I know in the UFC say, ‘Okay, I can take it. I’ll walk away now.’”

Penn was set to rematch top rated welterweight, Jon Fitch at UFC 132 on July 2^nd before injury ruled both fighters out of action. In his previous fight the Hawaiian had been totally dominated in the third round by Fitch, leaving him questioning whether he should hang up his gloves for good.
