WASHINGTON (AP) -- Mike Tyson's career apparently ended in yet another shocker Saturday night when he quit on the stool after taking a beating in a foul-filled sixth round against unheralded Kevin McBride.
Tyson lost for the third time in his last four fights, and once again he faded badly as the rounds went on before deliberately head butting McBride in a desperate attempt to end the fight in the sixth round.
"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."
Tyson was out of gas when he was pushed to the canvas as the sixth round ended, his head stuck between the first and second ropes. He stayed there for several seconds before finally untangling himself from the ropes and wobbling back to his corner.
