No, he just signed a 6 fight contract. I would maybe like to see him hang up the gloves but there isn't a chance he will, nor the UFC will let him. The UFC will throw him in next with a top dog and he will be put right into Title contention again and a guy like Cormier would smash him, but Manuwa, Phil Davis, and Chael are also options moving forward where I think he has a decent chance of winning. Guys like Cormier, Jones, Gus and Glover and Evans are a bit to much at this point in Henderson's career. Any one he fights he has a chance against, on any day if he lands a Bomb.
Fedor Emelianenko is the Greatest P4P MMA fighter to ever walk the earth, hands down.
