David Haye has stunningly suggested Jake Paul could suffer permanent damage in his shock clash with Anthony Joshua.Paul has gone against the advice of the masses, and lured former two-time heavyweight world champion Anthony Joshua into a huge December 19 showdown.

In reality, it shouldn’t go ahead.”Haye’s advice is chilling and worrying, and a thesis shared by many who are against the fight.Even Paul’s own mother has admitted she is terrified at the prospect of the pair stepping in the ring.Is Anthony Joshua vs Jake Paul safe, what are the rules?Paul vs Joshua will be professionally sanctioned with the relevant medical procedures in place, as there would be in any boxing event.Sanctioned professional fightEight, three-minute rounds10oz glovesAnthony Joshua cannot weigh above 245lbsMedical examinations will be conductedThe pair will fight in 10oz gloves over eight rounds under traditional Queensberry rules.A qualified referee will look to stop the fight at the appropriate time to protect Paul if he is taking too many punishing blows.To even enter the ring, Paul must go through a series of strict medical examinations, just as veteran Mike Tyson did for their clash last November.Of course, there is still the danger that Joshua’s shots could inflict damage on the night, with Paul having never faced an operator with as much punching power as the former champion.But he has previously sparred heavyweights and will hope his training is enough to prevent him sustaining any lasting damage.What has Jake Paul said about the risks of facing Anthony Joshua?Ultimately, Paul is complicit with the risks.The Miami clash next summer has not got Haye’s blessingThe SunPaul is in no doubt he will do a job on Joshua despite their past careersGetty‘El Gallo’ has kept to his word and is trying his best to make the impossible a reality at every step of his controversial boxing career.And in his same brash style, the 28-year-old has boldly declared he will knock out Joshua and cause a seismic upset.He said: “A professional heavyweight fight against an elite world champion in his prime. “When I beat Anthony Joshua, every doubt disappears, and no one can deny me the opportunity to fight for a world title.
