Jake Paul has been left unhappy with Mike Tyson's antics since delaying their heavyweight showdown.
Tyson was forced to reschedule his planned July 20 bout with Paul to November 15 after suffering an 'ulcer flare up' which prevented him from training.
Paul is persistent on fighting the heavyweight legend but concerns have been raised over the 58-year-old's health.
'Iron Mike' hasn't yet returned to training and Paul's advisor Nakisa Bidarian has revealed the influencer was not happy with the boxing icon partying since the fight has been postponed.
He told the MMA Hour: "He's doing great and Jake is p***** because he sees in Europe, living life, doing appearances, celebrating his birthday.
"And he's like, 'I thought he was injured, what's going on?'
"I talked to team Tyson yesterday and they said he's back, not doing boxing training but doing strength and conditioning and he feels great."
Despite concerns for the fighter's health, Bidarian went on to defend Paul over his decision to progress with the showdown.
He added: "Anyone can get an ulcer, or an injury. Mike Tyson and Jake Paul make sense because of the age, from my perspective.
"If Mike was in his early 30s, given Jake’s experience, there’s no sense to that fight.
"Age is the equalising factor. When you look at Mike Tyson at age 27, he was 40-1. Jake Paul is 27, he’s 9-1.
"Jake Paul’s been a professional for four years, at that point, Mike Tyson was a professional for 14 years.

"If you ask the vast majority of the public, everyone thinks that Mike Tyson is gonna knock out Jake Paul.
"I think as long as he has a clean bill of health, which he did, and he 100 per cent will if we move forward with November 15, then of course that fight should happen."
Tyson is way past his prime and has suffered with a whole host of health conditions in recent years, including sciatica which left him using a walking stick.
There has been much criticism in the boxing world that the fight will be sanctioned professionally, given the legend's current condition.
After his medical concern prevented him from training, Tyson has been making appearances around the world including in Dutch capital Amsterdam.
But he has yet to return to full training with over four months to go until the showdown takes place.
Paul has previously admitted he is 'nervous' to step in with the notorious power-puncher, who has shown he still retains an element of his ferocious hitting in training footage on social media.
The YouTube star is currently in training in Puerto Rico, as he prepares to face replacement opponent Mike Perry, where a win would stand him in good stead to face the veteran later in 2024.
