Mike Tyson admits he still hasn't fully recovered from his loss to Jake Paul more than two months ago.
The 58-year-old boxing icon was beaten convincingly on points by Paul in November in a controversial crossover clash at Arlington's AT&T Stadium.
Tyson looked like a shadow of his former self as he laboured to the final bell against a man 31 years his junior.
The clash resembled more of a sparring session than an actual fight, with Paul admitting in the immediate aftermath that he held back from trying to knock out Tyson.
In total, Paul landed just 78 punches while Tyson connected with 18 of his blows.
However, it still took a tremendous toll on 'Iron Mike's' body.
"I don’t know if I’m 100 per cent recovered, but I feel good," he told the New York Post over two months after their November 16 date.
Tyson may not be fully recuperated but that hasn't stopped him from stepping back into the gym.
The boxing legend shared some pictures on his Instagram of him using the seated row machine in the weight room.
He captioned the post: "Subscribe to the tribe," in reference to his clothing brand Tyson 2.0.
Tyson wasn't pictured doing any boxing training, although he has admitted he would be open to fighting again.
"I don't think so,” Tyson said in the ring after his defeat to Paul when asked if it was his final fight. “It depends on the situation.
“I don’t know, maybe I’ll fight his brother [Logan Paul].”
If Tyson was to return to the ring, it wouldn't be a popular decision.
Fans were extremely concerned about his health leading up to the fight and those fears were stoked further when the Hall of Famer admitted he could barely remember his eight-rounder with Paul.
Speaking to Fox Sports Radio he said: "I don't remember the fight that much, I kind of blanked out.
"I haven't watched the fight. You know what I remember.
" I remember coming back from the first round and Jake was doing some sort of bow.
"That's the last thing I remember. I wasn't tired, I wasn't sweaty.
"I went to the house we were staying in, I left the house with my wife and kids, went to the after-party then went back."
