Mayweather v McGregor: Fight details
Floyd Mayweather had little interest in engaging with the crowd and as seen above was wearing a subtle little number! Floyd said both fighters owe the crowd an entertaining fight and he was confident it won't go the distance.
McGregor was the fans favourite. He made a point of meeting and greeting huge numbers of supporters and said Ireland will take over Vegas this weekend. He too doesn't feel it will go the distance, predicting he'll knock Mayweather out in the first round.
The highlight of Tuesday really was the incident between McGregor and Paulie Malignaggi which culminated in the below, remarkable, Malignaggi rant. It's quite biological too.

We also got two good interviews with two of the calmer characters on show today. Both Nathan Cleverly and Badou Jack oozed calm, steely confidence ahead of their light heavyweight showdown on the undercard.
It's been a long day in 40 degree heat. Time to cool down with a bud light or any other low carb beer...Paulie may be reaching for one too.
Undefeated boxing legend Floyd Mayweather is Sky Bet's odds-on favourite to win Saturday night's huge showdown in Las Vegas at 1/4 but most of the money has been piling in for UFC star Conor McGregor to cause an upset, forcing his odds to be cut to 3/1.
If you fancy a flutter, Sky Bet have over 30 markets and a whole host RequestABet specials to get involved with so we've picked out a selection for fans of both fighters to check out...
