Jake Paul learned a tough lesson Thursday night: Don’t step on Mike Tyson’s foot. 

The fighters met Thursday for their final weigh-in before facing off in a highly anticipated matchup at AT&T Stadium Friday night.

But things took a drastic turn when the former heavyweight boxing champion slapped the YouTuber turned boxer on stage.

Tyson cleared the air, telling the New York Post it was because Paul stepped on his foot, maybe on purpose. 

“I was in my socks, and he had on shoes,” Tyson told the outlet after the weigh-in. “He stepped on my toe because he is a f—ing a–hole. I wanted to think it happened by accident. But now I think it may have happened on purpose.”

“I was in a lot of pain. I had to reciprocate,” he added.
