I predict Tyson is winning the fight, but midway through he collapses from a heart attack or a stroke or something. Paul tries to save him by performing CPR, but in his panic he forgets to remove his gloves, rendering the chest compressions ineffective. When Paul goes to give Tyson rescue breaths, Tyson summons the strength for one last attack and bites off part of Paul's ear, just before succumbing to his cardiac event, and Paul is deemed winner by disqualification.
