1:00am EST

Floyd Mayweather defeats Conor McGregor by 10th round TKO. McGregor was exhausted at the end, and Mayweather poured on the shots and gave Robert Byrd no option but to intervene and end the contest. McGregor gave it one hell of a shot, but it was not to be.

Mayweather now moves to 50-0, the first fighter to ever reach that mark. 

12:52am EST -Round 10

Both men look tired but Mayweather is pouring it on, hurting him badly, and the referee Robert Byrd stops the fight. It’s all over.

12:50am EST -Round 9

McGregor hurt Mayweather with a body shot, but the referee ruled it a low blow. McGregor is throwing a lot of punches that don’t seem to hurt Mayweather, and it is the latter who is landing the power shots. Mayweather hurts McGregor badly with a right hand and the Irishman is on shaky legs. He holds on to his opponent for dear life and looks out on his feet. McGregor barely makes it out of the round.

12:46am EST -Round 8

Mayweather seemed to turn his back to McGregor again. The Irishman lands one nice shot, but Mayweather agains walks down his opponent and is the aggressor. McGregor rallied with some nice shots in the last minute, but this was a very close round with both men having good moments in the stanza.

12:42am EST -Round 7

We are now in the second half of the fight. Again it is Mayweather, the famed counter puncher, walking down McGregor and landing hard rights. There seems to be a little less pop on McGregor’s punches, is he tiring? Mayweather snaps McGregor with some right hands. McGregor is fighting more with his hands down and has to rely on his reflexes. McGregor looked a little gassed at the end of the round.

12:38am EST -Round 6

Incredibly, Mayweather turned his back on McGregor and the Irishman took full advantage by throwing shots until referee Byrd intervened. Mayweather is throwing some bombs now on McGregor and landed some hard right hands. It looks like Mayweather tried to finish the fight there, but McGregor recovered. Mayweather landed another hard right towards the end of the round. It’s been a very interesting first half of the fight.

12:34am EST - Round 5

Both men are manhandling each other and roughing the other up. Mayweather is walking down McGregor, who is employing some good head movement to avoid shots. There was a lot of holding and clinching in the fifth, and after the bell, Mayweather pushed McGregor in the chest.

12:30am EST -Round 4

McGregor starts the round strong and unloads on Mayweather against the ropes. The American indicated that he was hit under the belt but did not seem hurt. Mayweather landed a nice left and is upping his volume of punches. Mayweather is targeting McGregor’s body a lot and staring to walk McGregor down. This could be a turning point in the fight.

12:26am EST -Round 3

McGregor is warned again by referee Byrd for throwing hammer fists. McGregor is trying to manhandle Mayweather more. The fighters almost clashed heads midway through the round. The Irish man found a home with some sharp jabs in the third, but Mayweather threw some solid body shots on McGregor in the last minute of the round.

12:21am EST -Round 2

Again, Mayweather is working off the ropes. McGregor is warned for punching on top of the head. Mayweather looks very relaxed. McGregor switched his stance mid-round and again is much the busier fighter. Mayweather is not throwing many shots, and his inactivity is giving McGregor some momentum in the fight.

12:17am EST -Round 1

McGregor goes straight on the front foot. Mayweather is working from the ropes, and looks pretty relaxed. McGregor showed off a bit and put his hands behind his back. Both men are feeling each other out and not over committing. Mayweather has been able to dodge all of McGregor’s shots, but the big shot of the round was an uppercut from the Irish man, which might have won him the round.

12:13am EST

And there's the opening bell.

12:12am EST

In the final fight before the main event, Gervonta Davis defeated Daniel Fonseca by 8th round KO.

Davis appeared to hit his opponent behind the head, and Fonseca hit the canvas. Fonseca went down and did not beat the count. Davis was not a very popular winner with the crowd tonight.

The next fight is the one we have been waiting for.

“I’m all business on fight night. I do not care about his records or achievements. A fight is a fight,” says a composed and focused McGregor.

On what he sees happening: “I see me truly outclassing this man, and putting him to sleep.”

On how he will do it: "I'm going to go out, be myself, be free, be spontaneous, and paint a beautiful picture.”

The pay-per-view has started, we are getting closer to the big fight.

The man in the middle for the main event tonight is Robert Byrd, who is no stranger to big fights. Byrd was the referee for the Ward/Kovalev 2 fight in June, which Ward won via 8th round TKO.

Both fighters were reportedly happy with this choice. Byrd’s wife, Adalaide, has adjudicated MMA fights in the past, so there is a history of involvement in both combat sport codes in the Byrd family.

Oh, and in case you are wondering who will sing Amhrán na bhFiann later on, wonder no more:

Yesterday’s weigh-in saw Floyd Mayweather Jr. tip the scales at 149.5 pounds, while McGregor came in at 153 pounds. The contract weight for the fight was the light middleweight limit of 154 pounds. It’s not unusual for Mayweather to come in light, as his optimum fighting weight is around the 150 mark. McGregor, though, came in a full pound under the limit. Has he overtrained, or has his team tapered his training just right?

After rehydrating, McGregor is reportedly set to walk into the ring at near 170 pounds, and we'll see if he uses that size to try and manhandle Mayweather or not.

Will it be a one-sided beatdown for the 49-0 American, or will McGregor somehow shock the world. We'll find out later! Stay tuned for updates over the course of the evening!

----------------------------------------------------------------------------------------------

The boxing match will be a 12-round contest, which will be shown in more than 200 countries and territories. Over the past few days private jets have reportedly been ferrying celebrities to Vegas. There are also reports that bets worth more than a million dollars have been placed.

Of course, Notorious McGregor has vowed he will win within two rounds and even Mayweather has speculated that due to his years out of the ring the fight could lean towards McGregor.

Bookies, who are saying that this is shaping up to be one of the most heavily wagered boxing matches in history, are getting 12 bets on McGregor for every one on Mayweather, but the amount of money is stacked in Mayweather's favor, so it's still a tough call.
