The pair will settle the score at the AT&T Stadium in Dallas, Texas, in front of up to 80,000 fans. Both Tyson and Paul were due to fight back in July, but 'Iron Mike' was . Despite concerns for the 58-year-old's health, the former undisputed heavyweight champion has insisted he will be fit to make the walk to the ring.

Friday's heavyweight dust-up will see Paul and Tyson go glove-to-glove in a professional showdown in an eight two-minute round format - as opposed to the more standard three-minute rounds. The sanctioned fight has already been approved by the Texas Department of Licensing and Regulation. Both boxers will wear 14-ounce gloves, heavier than the standard gloves.

The two boxing stars will be subjected to drug testing before they touch gloves in their blockbuster showdown. The Texas Department of Licensing and Regulation told World Boxing News: "Contestants who fight in Texas are subject to random drug testing. Combatants over the age of 36 are also required to pass an EKG and an EEG."

Paul - who recently - clarified the drug-test rules for the fight. O'Malley's coach, Tim Welch said: "They've got to let Mike use some special supplements, a little bit. I mean 58-years-old. Having the lifestyle that he's had, his natural testosterone can't be that high, so hopefully he's able to get boosted up a little bit."

Replying to the comments, 'The Problem Child' said: "Well, there's like a big, panel, drugs test from the Texas State Commission." Welch then joked: "So his testosterone can't be 16,000 like Alistair Overeem that one time," with Paul replying: "No, I don't think so."

Back in August, Tyson admitted , adding that he “always trains on mushrooms.” Appearing on Logan Paul’s Impaulsive podcast with Mike Majlak, Tyson was queried on his “bout with marijuana. I never had a fight, it’s always been my friend,” the legend said.

Alongside Logan and co-host Mike Maljak, Tyson spoke about his previous use of Marijuana before the topic of conversation turned to magic mushrooms and the pro-boxer produced a bag full of spores. Maljak asked: "Are you going to take these shrooms today?" before Tyson replied: "I have to take them when I train. I always train on my mushrooms."

Shocked, Paul asked: "What? Why?" before Tyson explained: "Because I feel beautiful. They take me to heaven baby." Moments later, a confused Paul asked Tyson if he would be under the influence of magic mushroom's during his fight with his younger brother, to which the boxer explained: "If I'm not on mushrooms I'll be on..." before Maljak joked: "PCP?" Tyson smiled: "That's a good one too," before adding: "Residue of mushrooms. I won't be on mushrooms but I'll be on the residue of mushrooms."
