    Mayweather v McGregor
  2. Calm v screaming

    So, what just happened?

    This picture sums it up very, very well.

    Weigh in

    Both fighters make the weight, and McGregor was the one doing all the screaming and shouting, while Mayweather just watched on and then laughed.

  4. 'Weight doesn't win fights, fighting wins fights'

    Now some quotes from Floyd Mayweather, who says: "I have been here before, I know what it takes, tomorrow it comes down to the fighters.

    "Weight doesn't win fights, fighting wins fights. It will not go the distance, mark my words. I just want to thank the fans, this will be Conor McGregor's last fight as well.

    "The fans can't fight for you it comes down to the two competitors. Forty-nine times I have been out there and it is one-on-one."

  5. 'I see a man afraid'

    Conor McGregor says: "I'm going to breeze through him. I'm a professional, I make weight, it is sacrifice but I make it, I'm ready.

    "I will be a lot bigger, a lot bigger than him, close to 170lbs. There is a saying you will never beat the Irish, Las Vegas is Ireland now. I'll stomp my foot right in the centre of the ring. I see a man afraid and you will see that tomorrow."

  6. Post update

    McGregor is the one doing all the talking, he looks fierce and ready to go. He is trying to provoke Mayweather, who remains ice cold. The American just laughs in his face.

  7. Post update

    And now the head-to-head.

  8. BreakingBoth fighters make the weight

    McGregor weighs in at 153lbs (10st 13lbs), one lb under the 154lb limit. Now Mayweather, and he weighs in at 149.5lbs (10st 9lbs 8oz), well inside the weight limit.

  9. Here comes Mayweather

    McGregor's fans are outnumbering Mayweather's with boos ringing around the arena as the American makes his way to the ring.

    Mayweather is flanked by his huge bodyguards that have not left his side while in Vegas, as part of an entourage of about 100. Incredible.

    It is a slow, slow walk to the stage, accompanied by the sounds of the Phil Collins' hit 'In The Air Tonight'.

    Anyone have Mayweather down as a Phil Collins fan? Nope, me neither.

  10. Fines if you don't make the weight

    There has been an issue of whether McGregor would make the 154lbs limit, with Mayweather saying the Irishman 'looked 10lbs over' earlier in the week.

    If that does happen, the fight will almost certainly still go ahead, but 'a heavy fine' would be placed on him, well, according to Mayweather.

  11. Here comes Conor

    Conor McGregor, with an Ireland flag wrapped around his shoulders, is waiting to be called to the stage.

    He bounces around on his toes, a bit of nervous tension, and here he comes, with thousands and thousands of fans desperately trying to record the action on their phones. It is an event they will never forget and never want to forget.

    Martyn Waugh: I can see McGregor outboxing Mayweather. Mayweather isn't nearly as skilled as McGregor when it comes to pure boxing. I think McGregor will pick him apart with his famous jab and win on the scorecards unanimously.

  13. Cleverly makes the weight for title defence

    Earlier on, Wales' Nathan Cleverly, who defends his WBA World Light-Heavyweight title against Sweden's Badou Jack on the undercard, successfully made the weight.

    We will have full text coverage of Cleverly v Jack in our live page tomorrow.

    The camera goes backstage and shows Conor McGregor looking super relaxed, playing with his toddler son looking like he hasn't got a care in the world.

    He will change his appearance from Family Man to Focused Man very soon.

    Stage

    This is where the two biggest names in sport this weekend will walk out. One great bit of news is Jimmy Lennon Jr is doing the MC work tonight.

    I do love the way he drags the Mayweather name out. "Floyd Monnnnnnnneeeeyyyy Mayweather".

    Arena

    If you've not been to the T-Mobile Arena, let me tell you it's impressive.

    Huge escalators inside hit home to the sheer size, you barely walk 50ft before hitting the next bar on the concourse and when you elect to take a seat it's a beautiful mix of strobe lights, banner lights circling the bowl-shaped arena and as always with boxing, the ring is like a magnet to the eyes.
