Tyson simply gives up after Round 6

In the fourth round, Tyson got McBride's attention with a left hook that brought many in the crowd to their feet. That was followed a few moments later by a right hand to the chin, and a left to the body that caused McBride to sag. It was Tyson's best round, but McBride weathered it. Two rounds later, Tyson had no more fight left in him, although he was ahead on two of the three judges' scorecards.
