Mike Tyson fuels health fears with dramatic sparring video ahead of showdown with Jake Paul

Mike Tyson has released ominous sparring footage that has some fans fearful ahead of their highly anticipated Jake Paul fight.

The former world heavyweight champion, 58, will face YouTuber and former boxer Paul on November 15 at AT&T Stadium in Arlington.

The fight was originally scheduled for July, but Tyson suffered a medical emergency on the plane. An “ulcer flare-up” left Tyson feeling nauseous and dizzy before paramedics later came on board.

But Tyson, once considered “the baddest man on the planet”, is back in training for the rescheduled clash – his first sanctioned fight in two decades.

Earlier this week, the 58-year-old posted a short clip from his sparring sessions. In the video you can see Tyson supporting his sparring partner on the ropes.

Tyson's sparring partner collapsed into the ropes after a left hook from “Iron Mike”.

The former heavyweight champion then lands a left hook that drops his opponent towards the canvas.

This causes his trainer to stop sparring – much to the frustration of a pumped-up Tyson.

“Are you damn sure?” screams the 58-year-old. “I have a lot in me, I’m just getting started.”

Tyson is a huge underdog against Paul, who is more than 30 years his junior. But the clip has convinced some fight fans that “Iron Mike” can improve the odds.

“The passion in his voice tells me how bad he wants it,” one said.

“Imagine a world where 58-year-old Mike Tyson knocks Jake Paul unconscious. “It would be beautiful,” another added.
