DETAILS of Brock Lesnar’s huge $637,000 per fight deal with WWE have reportedly been revealed.

The wrestler who is known as the ‘Beast Incarnate’ was expected to leave the company to return to UFC when his contract expired on April 8 after WrestleMania 34.

But the wrestling world was shocked when the 40-year-old defeated Roman Reigns to retain the Universal Title at the Showcase of the Immortals.

News broke the next day that Lesnar had agreed an extension to remain with WWE — but speculation has been rife about what that entails.

And wrestling news website Dirty Sheets have claimed that the star is set to pocket a fortune.

It states that WWE will pay the ex-UFC heavyweight champ $127,000 for every TV appearance he makes, even without wrestling.

But when he does pull on his ring attire the real big money kicks in — with it stating Lesnar will net $637,000 per pay-per-view fight.

Although he has renewed ties with the company, the new contract is different to his old one after he penned an “image rights” deal with the company.

This allows WWE to use his likeness for merchandising at a price of $637,000 a year — the same amount UFC pay to him for the same thing.

Lesnar also receives a six per cent cut from his merchandise sales.

And it is not a fixed-term contract — which allows WWE to use and pay him when they need him.

The five-time world champion will be appearing on next week’s Monday Night Raw.

He will defend his title against Reigns again in a Steel Cage Match at the Greatest Royal Rumble in Saudi Arabia on April 27.
