UFC boss Dana White has revealed fighters went "crazy" after discovering how much WWE icon CM Punk was paid for stepping into the octagon.
Punk, real name Philip Jack Brooks, made his UFC debut in 2016, losing by first-round submission to Mickey Gall.
His second and final MMA contest came two years later against Mike Jackson which he lost by unanimous decision - before the result was later changed to a no contest after his opponent tested positive for marijuana.
But while his legacy in the octagon left a lot to be desired, his profile meant he received a fixed payment of around £400,000 for his debut against Gall.
And MMA Fighting claim various additional bonuses from the fight led to him taking home roughly £800,000.

Before White added: "Oh, yeah. People went crazy when they saw what he got paid. Even the women."
After Punk's defeat to Gall, then-UFC bantamweight Cat Zingano tweeted: "CM Punk made $500k on his entry fight while the rest of us pay to fight? Y’all should be ashamed UFC."
