ARLINGTON, Texas (AP) — Jake Paul and Mike Tyson traded insults and expletives as they previewed their fight just a few football fields from the site of the planned summer bout, the 80,000-seat home of the Dallas Cowboys.

As for substance, there wasn’t much Thursday night.

Paul downplayed the suggestion that the 27-year-old social media star-turned-boxer still hasn’t had a legitimate opponent, while Tyson simply refused to answer a question about his age. The former heavyweight champion will be 58 on July 20, when the fight is set for AT&T Stadium.

“I don’t see too many people critical about it. Look at this,” Tyson said, pointing to the raucous crowd at an entertainment venue near the site of the fight.

When a reporter suggested there were critics, Tyson said, “Who? Name me somebody. You? Who?”

The Texas Department of Licensing and Regulation is sanctioning the fight as a professional bout, but it will be eight two-minute rounds instead of 10 or 12 rounds lasting three minutes each. The gloves will be heavier (14 ounces instead of 10), which is supposed to reduce the power of punches.
