Former champion boxer Mike Tyson slapped fire out of boxer Jake Paul during weigh-ins, in Irving, Texas. Their boxing match is set to take place on Friday, Nov. 15 at AT&T Stadium in Arlington, Texas.

The weigh-in was held at the Toyota Music Factory in Irving, Texas on Thursday, Nov. 14.

Paul, 27, was talking trash and “purposefully” stepped on Tyson’s foot. Tyson, 58, hauled off and slapped Paul across the face. Tyson is still in good shape for a middle-aged man.

The two fighters were quickly separated by their handlers as Paul mocked Tyson and laughed at him.

Tyson weighed in at 233 pounds, and Paul weighed a career-high 220 pounds.

A source close to Tyson told ESPN that Tyson was fed up with Paul’s trash talking, and stepping on his foot triggered Tyson.

Tyson was escorted away while Paul addressed the crowd, saying, “It’s personal now. He must die!”

Bettors are overwhelmingly siding with Tyson. But someone in Michigan placed a $1 million bet with Caesars Sportsbook at -220 odds. The bet would pay $1,454,000 if Paul wins.

But others are convinced that the fight is a staged stunt. Many believe Tyson will take the fall and get knocked out by the younger fighter.

Tyson will be paid $20 million for the sanctioned fight, while Paul will receive $40 million.

It will be Tyson’s first fight since he retired from professional boxing in 2005 with a record of 50 wins, 6 losses and 44 knockouts.
