Revealed: What happens if Conor McGregor misses his weight for fight with Floyd Mayweather on Saturday

Floyd Mayweather called Conor McGregor “extremely heavy” in the week leading up to their highly anticipated super-fight on Saturday.

The American and Irishman are set to do battle at 154lbs, but there is every chance McGregor could weigh in too heavy for the bout.

Mayweather hit out at his opponent in the build up to the fight, accusing him of being a staggering 10lbs over the required limit.

“Conor McGregor is extremely heavy right now,” said Mayweather. “I think he’s 164 so he’s still got 10 pounds to go.

“I get that extra money if you can’t make the weight. Get those extra millions ready. UFC get those extra millions ready.

“You got to get that weight down like a true champion. A true champion is disciplined and very responsible but we’ll see.”

So what happens if McGregor misses his weight?

If the UFC star weighs in too heavy ahead of his boxing debut the fight will still go ahead – so fans who have paid a lot of money to be there need not worry.

In fact the only person who will be out of pocket is McGregor, who will be slapped with a fine for failing to fulfil his part of the contract.
