After what feels like years of build-up, Jake Paul and Mike Tyson will controversially share a boxing ring in a professional heavyweight showdown in the early hours of Saturday morning.
The two were originally set to square-off in the summer only for 'Iron' Mike to suffer an ulcer flare-up, meaning the bout had to be put back four months.
Speculation has remained rife that the former blue-riband division ruler is still suffering health issues though, leading many to believe that the fight could yet get cancelled once again, even at such a late stage.
However, as things stand, the fight remains on, but with so many questions surrounding the rules of the 'professional' bout, we thought we'd try and clear a few things up.
The Texas Athletic Commission have sanctioned Jake Paul v Mike Tyson as a professional bout, meaning the fight will count on both fighters records.
However a number of stipulations have been put in place given the current age of Tyson (58).
The fight will take place at heavyweight, meaning that Jake Paul and Mike Tyson won't have to make weight.
Typically, across boxing's many weight classes, fighters have to cut weight to make strict limits, however, that rule doesn't include bouts in the heavyweight division where boxers can come at any weight that they feel comfortable at.
Mike Tyson fought regularly at heavyweight during his successful and colourful professional career, whilst this weekend's showdown will represent Paul's first foray into the blue-riband division, having previously operated at cruiserweight and light-heavyweight.
There has been lots of conflicting stories suggesting the fight would last anywhere between six and 12 rounds, however, it's officially been confirmed that this bout will take place over eight two-minute rounds.
Typically, male fighters undertake 10 or 12 three-minute rounds, meaning fights last anywhere from 30 to 36 minutes - significantly longer than the 16 minutes that we are scheduled to witness in Jake Paul v Mike Tyson.
Both fighters will have to wear 14-ounce gloves, as opposed to the usual 10-ounce gloves.
The weight of the gloves is significant given that heavier gloves typically contain more foam padding than lighter ones, meaning it helps to absorb the impact of punches, and thus reduce the chance of strain and injury.

Despite earlier reports suggesting that both fighters may have to wear headguards, the fact that the fight is being sanctioned as a professional bout means neither man will have to wear a headguard.
Typically, amateur and white collar fighters have to don a headguard, but that won't be the case for Jake Paul v Mike Tyson.
Absolutely, and Mike Tyson will be gunning for a 45th knockout victory of his professional career.
'Iron' Mike made a career for himself with his ferocious and unprecedented power, earning the moniker of being 'the baddest man on the planet'.
Jake Paul meanwhile, has won seven of his eight bouts via stoppage too - including his July KO of Mike Perry in the sixth round.
Given the three decade gap between the two fighters, there was talk that knockouts would not be allowed in the contest, however, that has now been confirmed to be untrue.
No belts will be up for grabs this weekend.
There was some talk of a special belt being made for the fight, given the high publicity surrounding the event, but that will not be the case.
There are however numerous world titles on the line as part of the undercard, with Irish boxing star Katie Taylor and American ace Amanda Serrano squaring off in a hugely-anticipated undisputed super-lightweight rematch with the WBA, WBC, WBO, IBF and Ring Magazine straps up for grabs.
