Mike Tyson is back to feeling like iron once more … the boxing legend says he’s “100%” healthy again after suffering a medical scare on a flight over the weekend.

The 57-year-old required medical attention while aboard an American Airlines flight from Miami to Los Angeles on Saturday … but in a post on his X page on Tuesday morning, he revealed he’s doing just fine now.

Mike told his followers he’s at full strength … before he made it clear his plans to fight Jake Paul in July remain unchanged.

“Now feeling 100%,” he wrote, “even though I don’t need to be to beat Jake Paul.”

Tyson’s reps told TMZ on Monday the airplane emergency all stemmed from an ulcer flare-up the former heavyweight champ had just minutes before his flight was slated to land. The rep said Tyson was feeling “nauseous and dizzy” — and was appreciative of the medical responders who raced to tend to him.

Now healthy, Tyson will hit the ring yet again to continue his training for the Paul fight — which will officially go down in Arlington, Texas on July 20.
