Jake Paul facing long 'suspension' as Anthony Joshua set to lose $66 million of prize purse

Paul will actually walk away with more money than Joshua following their boxing bout.

Jake Paul will be stood down from boxing for at east 45 days following his sixth-round knockout at the hands of Anthony Joshua on Friday night. Joshua will also face a mandatory seven-day suspension, and the British star is set to lose about half of his $140 million prize purse as well.

Paul was hospitalised with a broken jaw after former heavyweight champion Joshua hit him with a thunderous right hand during their boxing bout in Miami. Paul posted an update on Saturday night, alongside an x-ray of his jaw broken in two places.

"Just got out of surgery. Everything went smooth," he wrote on social media after surgery to insert two titanium plates. "Thanks for all the love. Lots of pain and stiffness. Got to eat liquids for seven days."

Paul is now facing a medical suspension from boxing for at least 45 days - and likely more. The Florida State Athletic Commission has rules in place that prevent fighters getting back in the ring for at least 45 days after being knocked out.

Considering his injuries, the suspension can be extended to 60 or 90 days as well. Paul was given a 60-day suspension last year after beating Mike Perry, which came after being assessed by a physician. Considering he wasn't knocked out on that occasion, he's likely facing a longer layoff this time around.

Paul and Joshua will both be assessed by medical professionals after their bout, and even Joshua is required to stand down for seven days under boxing's rules. A close friend of Paul's revealed after the bout that initial assessments are his jaw will need 4-6 weeks to fully heal.

Why Anthony Joshua will lose $66 million of prize purse

Joshua and Paul both reportedly received about US$93 million for the fight - $140 million Australian. But because the fight occurred in America, Joshua is set to cop multiple taxes that will see him lose nearly half of the prize purse and walk away with less than Paul.

British star Joshua is set to be taxed by the US government for the earnings, as well as when he gets home to the UK. He'll also have to fork out some of the money in National Insurance contributions back home.

There's no state tax in Florida, but the US government is likely to charge an income tax of 37 per cent (about AU$52 million of the purse). Another $11.3 million will have to be paid to His Majesty's Revenue and Customs (British tax), and $2.8m in National Insurance contributions.

All up Joshua will part ways with about $66m, leaving him with $74m in his pocket out of the total purse of $140m. Paul will only be taxed the $52 million by the US government, meaning he'll actually get to keep more than Joshua.
