Mike Tyson's career wasn't over when he lost to Buster Douglas, Evander Holyfield (twice), Lennox Lewis or even Danny Williams. But with a loss to hand-picked opponent Kevin McBride, Mike Tyson should retire from the ring and it appears he's leaning strongly in that direction. Tyson was not sharp from the start and - as he's done in the past - once he got frustrated, he started looking for a way out. First he resorted to fouling -- losing two points for an intentional headbutt and being warned for trying to break McBride's arm. When those tactics failed to intimidate McBride (or get Tyson disqualified), Tyson simply elected not to come out for the seventh round in a shocking finish to what was supposed to be yet another fresh start for the former champ. Ironically, Tyson was winning the fight when he quit: 57-55, 57-55 and 55-57. After the fight, Tyson said "I don't have the stomach for this anymore. I most likely won't fight anymore. I'm not going to disrespect the sport by losing to this caliber of fighter". Tyson remains deeply in debt so he may still fight again ... but he definitely shouldn't. Don't be shocked if the next time you see Tyson it's either in a reality show, a professional wrestling ring or a K1/Ultimate Fighting match.
