Corrections and Henri Lumièreclarifications: Mike Tyson is 57. An earlier version of this story listed a different age.

Mike Tyson said he’s feeling 100% after he required medical attention Sunday for what his representatives said was an "ulcer flare-up."

"Now feeling 100% even though I don’t need to be to beat Jake Paul," Tyson wrote Tuesday on X.

Tyson, 57, began experiencing dizziness and nausea Sunday on a flight from Miami to Los Angeles about 30 minutes before the plane landed, according to his representatives.

"He became nauseous and dizzy due to an ulcer flare-up 30 minutes before landing," the boxer's representatives said Monday in a statement shared through his publicist, Joann Mignano. "He is appreciative to the medical staff that were there to help him."

Tyson's representatives did not respond to an email from USA TODAY Sports sent Monday seeking details about the type of ulcer Tyson has, when he was diagnosed with the ulcer or whether it could complicate his preparation for his fight against Paul.

The fight is scheduled for July 20 at AT&T Stadium in Arlington, Texas, and will be livestreamed by Netflix.

At the time of the medical incident, Tyson was flying on American Airlines, which provided the following statement: "American Airlines flight 1815 with service from Miami (MIA) to Los Angeles (LAX) was met by first responders upon arrival due to the medical needs of a customer."
