Conor McGregor vs Nate Diaz II

Mixed martial arts (MMA) superstar Conor McGregor has been fined $150,000 (£122,025) and must complete 50 hours of community service following an investigation by the Nevada Athletic Commission into chaotic scenes that took place during an eventful press conference with Nate Diaz in August.

The famously brash Dubliner, who currently serves as UFC featherweight champion and the increasingly popular $4bn company's most profitable figure, successfully avenged a shock submission loss to Diaz by defeating his arch-rival via majority decision at UFC 202. The build-up to that rematch was typically heated, with McGregor arriving fashionably late.

After more angry verbal exchanges, tensions ramped up a notch further during the closing stages of that Las Vegas media call and the session eventually descended into mayhem with both camps hurling plastic bottles at one another.

McGregor gave an unsurprisingly carefree public response to losing 5% of a $3m purse for his part in those unsavoury scenes, taking to Twitter to declare that: "I get fined more than these bums get paid." Diaz's case has yet to be heard.

"The Notorious" is due to return to the octagon on 12 November as the headliner for UFC 205 at Madison Square Garden, where he will continue to bounce around the divisions by challenging Eddie Alvarez for his lightweight title at the promotion's first New York show since the state finally past legislation to legalise MMA back in February.

The 28-year-old, who received a medical suspension of up to six months following that second bout against Diaz, has yet to mount a single defence of the featherweight strap he won with a brutal 13-second knockout of Jose Aldo in December 2015.
