Conor McGregor returns to the octagon for the first time in over two years on Saturday - or early Sunday morning if you're watching in Britain - in a UFC lightweight title fight against Russia's Khabib Nurmagomedov. The Irishman has not fought competitively since losing to Floyd Mayweather in a multi-million dollar boxing match in August 2016. This weekend's mixed martial arts bout, one of the most eagerly anticipated in recent years, is being shown live on BT Sport - before online streaming service Eleven Sports take over UFC rights from January 2019 onwards. Broadcast restrictions mean that fans in the UK who have subscribed to UFC Fight Pass will not be able to watch the bout live, only BT Sport subscribers will be able to see the live action. McGregor and the undefeated Nurmagomedov were supposed to face off in the final pre-fight press conference on Thursday - with the main event scheduled to take place at around 3am Sunday UK time - but the Irishman's late arrival led to Nurmagomedov carrying out his own press conference before leaving.
