The rumours are still swirling about a possible UFC fight between Floyd Mayweather Jr. and Conor McGregor.

The duo made a lot of money when they fought inside a boxing ring and both could be in for another huge payday if they decide to step into the octagon to fight in a MMA contest.

Mayweather went into the boxing match as a huge favourite and emerged victorious and bookmakers are expecting the exact opposite if the duo meet in the UFC.

Las Vegas bookmakers Bovada, are offering odds of 11/2 for a Mayweather win, whilst McGregor is priced at 1/9. Ironically, this is pretty much the reverse of the odds they set for the boxing contest, when ‘Money’ was the clear favourite.

Whether the undefeated boxer Mayweather fancies a trip into the octagon remains to be seen. He would, obviously, make a lot of money from a fight, with figures of up to $1billion being banded about, but he would be a massive underdog against McGregor.
