Boxing superstar Mike Tyson Thursday night slapped his challenger Jake Paul in the face during a staredown after the final weigh-in before Friday night’s match.

Tyson and Paul are set to face off in a Netflix special on Friday. The exchange came after Paul got close to Tyson after the weigh-in, prompting the boxing giant to slap the 27-year-old.

Paul did not react to the slap at the time, but claimed the fight was “personal now” after Tyson left the stage. He also claimed he didn’t feel the slap, but that Tyson “must die.” according to USA Today.

The moment was unusual for Tyson, who had remained calm with his younger opponent until the incident. Paul has previously mocked Tyson, even calling him “boring” during a press conference teasing the fight on Wednesday, but Tyson did not respond to the bait, by Fox News.

Tyson will fight out of the red corner on Friday night and weighs in at 228.4 pounds. Paul will fight from the blue corner of the ring and enter the fight at 227.2 pounds.
