Trash-talking fighters, loud music, cheering supporters... and that was just the pre-fight weigh-in. 

Large crowds of Irish fans gathered at the T Mobile Arena in Las Vegas on Friday to catch a glimpse of Conor McGregor ahead of Saturday's lightweight title showdown against Khabib Nurmagomedov.

With flashing lights and loud dance music, the expectant crowds were whipped into a frenzy as they waited for the main attraction. 

There were cheers and chants of ‘Olé Olé’ as McGregor eventually took to the stage for his weigh-in. 

In the early hours of Sunday morning, he’ll make his return to UFC following a two year absence, but appeared to be eager to get the action underway early, aiming a kick at Nurmagomedov during the ceremonial weight-in.

The pair both made the 155lb limit on Friday morning but tensions threatened to boil over at the ceremonial weigh-in for UFC 229 at the final staredown.

As they got into their fighting poses, McGregor brought his arms down on Nurmagomedov before aiming a kick at his bitter rival after being beckoned forward by the Russian.

McGregor made headlines for all the wrong reasons earlier this year, pleading guilty in a New York court to disorderly conduct after throwing a metal hand cart a bus carrying UFC fighters, among them his opponent tonight, Nurmagomedov.

At last night’s weigh-in event, footage of the bus incident and clips from TV news reports from the time were played on a big screen. 

It was accompanied by a dramatic, movie trailer-style voiceover asking if money and fame had taken their toll on McGregor.

Rather than ignore his arrest and subsequent court appearances, the UFC has turned the incident into a promotional video, adding to the drama of the sport’s most popular fighter. 

When I asked fans about it last night, the response was similar - yes Conor McGregor gets in trouble but it’s all part of his image. 

They would argue that you can’t claim the nickname ‘Notorious’ without breaking the rules from time to time.
