Boxing great Mike Tyson is keen to make up for lost time.

The former world heavyweight champion returns to the ring in Arlington, Texas on Friday where he will end a two-decade hiatus from the sport to take on the YouTube star Jake Paul — a man thirty years his junior — and he says that his return isn’t necessarily a one-night-only deal.

Tyson, 58, hasn’t competed professionally since a 2005 loss to Irish heavyweight Kevin McBride but did return to action four years ago for an exhibition contest with fellow ring icon Roy Jones Jr., but ahead of the fight which is expected to garner a huge live audience given its position on the Netflix streaming service, he says that he isn’t ruling out more fights in the future.

“Great. I feel great,” Tyson said to Manouk Akopyan, as noted by MMA Fighting. I’ve got the rounds in me. Listen, I’m sparring young guys, 30s, 20s, I’m sparring young guys and they’re hitting me real hard. It wasn’t a picnic when I first started training. I’m fighting with younger guys and they’re really giving me a shellacking at first. [Now] I’m doing my share.”

The bout, which will take place across eight two-minute rounds, has received criticism in some quarters given Tyson’s advanced age, as well as health issues experienced by the boxing legend which delayed the initially scheduled date this past summer.

“Thank you very much for being concerned,” Tyson said, addressing those who have expressed caution at the bout. “But I am fighting. I’m going to be okay… I was a different person then [when I retired]. “I was using narcotics, alcohol back then. I’m not that person anymore. I see a better picture of myself now. I see light. I see the world from a different perspective now.”

And should he roll back the years and score what would be the 45th knockout victory of his career, Tyson says he will assess any future challenges that might present themselves.
