Mike Tyson insisted on Tuesday he felt "100%" despite a recent health scare as he prepares for his July bout against Youtuber Jake Paul.

The 57-year-old former world heavyweight champion reportedly needed medical treatment on Sunday after complaining of nausea and dizziness during a flight from Miami to Los Angeles.

Paramedics boarded the plane at Los Angeles International Airport to treat the boxing legend before other passengers were allowed to exit the American Airlines flight.

The incident came as Tyson prepares to make a controversial return to the ring against Paul in Texas on July 20, which has raised fears that the fighter once known as the "baddest man on the planet" could be hurt due to his advanced years.

Tyson however insisted on Tuesday he felt fine despite Sunday's scare.

"Now feeling 100% even though I don’t need to be to beat Jake Paul," Tyson wrote in a brief post on X, formerly Twitter.

Tyson, who turns 58 in June, takes on the 27-year-old Paul in a professional bout which will comprise eight two-minute rounds. The fight has been sanctioned by boxing authorities in Texas.

Tyson has not fought a professional bout since 2005, although he did take on Roy Jones Jr. in an exhibition contest in 2020.
