Mike Tyson suffered a medical emergency during a Sunday flight from Miami to Los Angeles.

The professional boxer “became nauseous and dizzy due to an ulcer flare up 30 minutes before landing,” his rep told Page Six on Monday.

“He is appreciative to the medical staff that were there to help him,” the spokesperson continued, clarifying that Tyson, 57, is now “doing great.”

In Touch Weekly was the first to report on the “apparent medical scare” over the weekend, but Tyson’s rep clapped back at “false reporting that his medical attention caused” a delay prior to takeoff.

It was, instead, “due to air conditioning issue on the aircraft.”

This is a developing story.
