The fight isn't until Friday night. But Mike Tyson apparently didn't get the message during the weigh-in before his return to the boxing ring on Friday at AT&T Stadium. The boxing legend went after his opponent in front of hundreds of onlookers.

Iron Mike, whose last professional fight was a defeat to Kevin McBride in June 2005, weighed in at 16st 4lb, while Paul tipped the scales a pound lighter at a career-heaviest 16st 3lb. However, the pair clashed as they went head to head, with Tyson hitting Paul with a huge right-handed slap across his face.
