The slap heard 'round the world struck Jake Paul on the left cheek Thursday night. Mike Tyson whipped his open-palmed right hand across Paul’s face at the weigh-in before their wild and weird and puzzling event.

After months of buildup, Jake Paul and Mike Tyson will face off at AT&T Stadium. Paul (10-1, 7 KOs) hopes to add one more win to his growing boxing resume, while Tyson (50-6, 44 KOs) returns to the ring in a sanctioned fight for the first time since 2005.
