Jake Paul and Mike Tyson are set to fight in a major professional boxing match tonight. Here's how to watch and what time the bout starts.

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.

Paul and Tyson will fight in eight, two-minute rounds rather than the standard 10-12 rounds at three minutes each. There will also be a difference in the gloves worn. Both fighters will wear heavier 14-ounce gloves rather than the usual 10-ounce gloves.
