I don't know how the judges are going to score these rounds because it's so difficult to see who's got the advantage. Raquel Pennington has probably been trying to chase the more damaging strikes, the combinations coming forward.

This is such a strange fight. It just hasn't happened here. Holly Holm's tactics are so strange. We could have another controversial fight ending here.

Holly Holm has had Raquel Pennington up against the fence for most of the first two rounds.

Conor McGregor divides opinion amongst these Irishmen.

BBC Sport spoke to fans at the UFC 246 weigh-ins to find out who they would like to see win, the Notorious or Cowboy.

"The MMA industry is such a forgetful game. One guy can win and they're top of the world, and then a guy can have a loss and he's at the bottom."

That was Conor McGregor, getting philosophical on his YouTube channel before his first bout since October 2018.

So is this a fight to stay relevant?

There have been some suggestions McGregor has been losing fans at home in Ireland, external - but ticket sales for this fight show he remains a big draw in the sport.

Holly Holm has been pacing up and down the octagon. She looks pumped, just like she did before taking Ronda Rousey's 'O'. They're under way in Vegas.

Jeremy Renner, who plays expert archer Hawkeye in the Avengers film series, is in attendance tonight. If there’s anyone here who has pinpoint accuracy with their strikes, it’s him.

We've just seen Matthew McConaughey too...and Nick from the Backstreet Boys (ask your Mum)

Holly Holm has been here before. She knows what it takes to pick herself up off the floor and dust herself down.

A veteran of 77 recorded professional fights - across boxing (38), kickboxing (22) and mixed martial arts (17) - this is not the first time 'The Preacher's Daughter' has stood at the crossroads in her fighting life.

The former UFC bantamweight champion, who climbed on top of the MMA world with her unforgettable 2015 head-kick knockout of Ronda Rousey, faces off against a familiar foe in Raquel Pennington at UFC 246 in Las Vegas.

Holly Holm and Raquel Pennington are getting ready to step into the octagon in the co-main event.

Conor McGregor has fought on 18 January once before in the UFC. The last time was in 2015 in Boston, USA, where he stopped Dennis Silva with a second round TKO. The travelling Irish will be hoping for a similar result tonight here at the T-Mobile Arena.

Inside tonight’s UFC 246 programme, Dana White sends a note to the fans... “Conor wanted someone who is going to meet him in the center of the Octagon and throw down with him.”

Sounds like the Irishman wants a brawl...

But which way do you see it going?

Are you glad to see McGregor back? Do you like the mellowed version or would you rather see the Notorious of old?

So what styles are we going to see tonight? We had an MMA expert Eric Nicksick talk us through it.

We all know about Conor McGregor's left hand but Nick explains why it's so lethal. He also talks about how McGregor could bring cage control and body shots into play.

As for Cowboy, he's expected to use a kick to jam up McGregor's left hand before getting in close and working the body.

As for the winner? Nick feels the longer the fight goes on, the more it swings in Cowboy's favour.

BMF champion Jorge Masvidal is in attendance at the T-Mobile Arena tonight.

The title was specially commissioned for the fight between Masvidal and Nate Diaz at UFC 244 in November, which Masvidal won.

The American welterweight has been touted as a potential opponent for McGregor if he beats Cerrone here tonight.

What a fight that could be...

So we've used 'FU' and 'BMF' in this and a few of those last entries. What do they stand for? We can't tell you. But ask my friend Google and they'll be able to sort you out.

Talk about making an effort... This Conor McGregor fan spent approximately £1,000 on a replica FU suit and is rocking it.

We've just seen Conor McGregor arrive at the T-Mobile Arena, in a sharp suit as per.

And in the build-up we caught up with David August, McGregor's personal tailor and the man behind the Irishman's infamous pinstripe suit.

After being a professional bull rider, Donald Cerrone has had 50 MMA fights, racking up 36 wins. But in true cowboy style, Cerrone owns his own ranch - the BMF Ranch in Edgewood, New Mexico.

He bought the ranch just over 10 years ago after moving to Albuquerque from his home in Denver. This is where Cerrone lives, sleeps, trains and enjoys a lot of his downtime.

The ranch is extraordinary., external There is a gym, where fighters come to train from all over the world, complete with dormitories for the athletes to live in.

He raises his own animals, including goats, turkeys and pigs, which he kills for food.

There's a shooting range, a huge sauna and even a paintball arena. And the most amazing part of it? Cerrone built it all himself.

He was unsure about getting the ranch but a friend told him "if you build it, they will come".

But what about his 'Cowboy' nickname? "I wear boots and a hat," he told the UFC., external Nuff said.

I don't think we're going to see anything like that [the Khabib melee] tonight - at least I hope not anyway.

But when Conor McGregor competes, something incredible always happens, so hold onto your seats because we're in for a crazy ride.

The pair have been surprisingly cordial in the build-up though. You can watch the news conference in full on iPlayer by clicking here.

Has Conor McGregor mellowed after reaching the grand old age of 31? Has fatherhood seen him mature? Was he humbled after being dominated by Khabib Nurmagomedov last time out?

Certainly appears so. We can still expect fireworks though.
