Mike Tyson's boxing career is over. Again. This weekend he lost to Ireland's Kevin McBride, whom Tyson was favored to beat handily. According to the AP, although Tyson was winning the fight on the score card, the tempo had changed and he gave up after the 6th round and refused to come out of his corner.

"I don't have the stomach for this anymore," Tyson said. "I most likely won't fight anymore. I'm not going to disrespect the sport by losing to this caliber of fighters."

So, the man who intentionally bit off both of Evander Holyfield's ears doesn't want to disrespect the sport. This wouldn't ring quite so hollow if Tyson had at least fought a clean fight before giving up.

Tyson was weary by the fifth round and, in the sixth round, he was penalized two points for deliberately head butting McBride and opening a cut over his left eye. The head butt came after Tyson appeared to try to break McBride's arm in a clinch like he once did against Francois Botha and after he hit him with several low blows.

At least he's not disrespecting the sport. For his defeat, Tyson got $5 million, most of which was snapped up by his creditors. McBride earned $150,000.
