Mike Tyson, Jake Paul exchange insults as second joint press conference turns darker. If there’s a script for the promotion of the Mike Tyson-Jake Paul fight, it flipped on Thursday.

The boxers finally took the gloves off —metaphorically, that is — as they exchanged insults rather than smiles.

Three days after a playful faceoff between the fighters fueled speculation the fight is rigged, the tone was noticeably darker and more contentious when Tyson, 57, and Paul, 27, appeared at a press conference in Arlington, Texas.

Unlike New York, the site of the kickoff press conference Monday, the crowd helped set the tone when it greeted Paul with boos and broke into profane chants of “(Expletive), Jake Paul!’’ Paul chanted along and Tyson joined in, too, during an event to hype the heavyweight bout, which is scheduled to be held July 20 at AT&T Stadium in Arlington, Texas.

The fighters, prompted by emcee Brian Custer, addressed speculation their heavyweight boxing match is rigged. “Well, clearly they don’t have a high IQ in here, but that’s,’’ Paul said. NEW YORK — For the first time since arguably the most curious pairing in recent boxing history was announced, Mike Tyson and Jake Paul met face to face.
