The Big Show issued terrifying warning to Floyd Mayweather before boxer broke his nose

The Big Show issued a chilling warning to Floyd Mayweather over him breaking his nose to set up their massive WrestleMania match.

Back in 2008, Mayweather swapped the boxing ring for the wrestling ring, appearing from the crowd at the 'No Way Out' event to confront the 'World's Largest Athlete' after he tried to attack Rey Mysterio.

The undefeated boxer, flanked by his crew from 'The Money Team', jumped into the ring, and after Big Show dropped to one knee, he caught him square in the face after unleashing lightning quick punches.

The giant's nose was busted open and blood streamed. The stunt was planned, with Big Show encouraging Mayweather to break his nose for real.

However, at the same time, the 7ft monster let 'Money' know that he had to make a quick escape before adrenaline kicked in and things got really ugly.

Recalling the story on Insight with Chris van Vliet, the wrestling legend said: "There was such a size difference and they're like, 'How do we make this believable?'. I said, 'It's easy, I'll get on one knee because I'm so big and arrogant' and I said, 'Just have him break my nose'.

"Floyd's a pro. I said, 'Don't break the bone just give me a little tap'. If we don't make it look like something's happening nobody's going to buy it. We need to get this off the ground running so people go 'Oh damn!'.

"I said, 'But when you bust me in the nose and it bleeds, run. Because there's going to be five to 10 seconds that I'm not going to be in the right frame of mind. If I get my hands on you, I might hurt you and you're worth half a billion dollars so make sure you're not around'.

"As soon as that hot blood hit the back of my neck I was p***ed, even though I know it's a work.

"I remember tearing ass after him, I remembered I grabbed one of his guys that I thought was him and that guy started going, 'It's not me!'. He started screaming because I had him by the upper hip, the lower love handle and the ribs in one hand. He wasn't going anywhere."

Pure chaos ensued, with Big Show nearly trampling on Mayweather's team as they darted over the barricade.

The five-weight world champion wasted no time scarpering and in the 2011 'The Big Show: A Giant’s World’ documentary', Triple H recalled that he saw a panicked Mayweather in the hallway and he shouted to his manager Leonard Ellerbe, ‘Let’s get out of here, he’s gonna kill us!’.

Mayweather earned huge pay packet from WrestleMania match

Big Show continued: "He got in his car and he left. Like, 'Nope, not hanging around, this is not for me. We had to call him and his manager to come back. He stuck his head in Vince's [McMahon] office and he said, 'Are we cool man?'.

"I said, 'Dude, you did awesome' and I gave him a big hug."

Initially set to be a tag team match involving Batista and Mysterio, Mayweather and Big Show squared off in a no disqualification match at WrestleMania 24, with the 50-0 fighter reportedly making $20 million and scoring the victory after a brass-knuckle assisted knockout punch.

"We had to talk him out of doing stuff," Big Show said of working with Mayweather.

"He wanted me to chop him, body slam him through a table. He wanted all this crazy stuff.

"When I threw the guy out of the ring, we had to do a double because he wanted that to be him.

"I remember after that WrestleMania, getting assaulted by his grandma. She slapped the bejesus out of me for beating up her grandbaby. Floyd had to come over and calm her, she was mad.

"Because I stood on him. That's what she was mad about, that I had stood on him. Her and I became friends later on but when we first got back there, she was ready to rip my ass apart."
