Netflix is hosting its first major live boxing match on Friday with Jake Paul vs. Mike Tyson, part of its efforts to expand into live content, which also include hosting Christmas NFL games.

Tyson responded by slapping Paul, and the pair were quickly separated by security, according to the video. Paul responded by laughing at him and playing to the crowd. “It’s personal now. He must die!” Paul told the crowd at the press conference, per NBC News.
