If you bump into the Trinity Street massive this morning and wonder why there's big black bags under our eyes, it's largely down to the UFC phenom that is Conor McGregor.
At about 5.30 am, the UFC's hottest property took to the octagon to dispose of Dennis Siver and set up a monstrous clash against lightweight beltholder Jose Aldo. Unsurprisingly, there was more than a few familiar names who eschewed a night's sleep to watch the Crumlin man, and they took to Twitter both before and after the fight to sing the praises of The Notorious one.

There was, however, some bad news for Irish fans; McGregor's title shot will be taking place in Vegas, as opposed to Croke Park. UFC supremo Dana White conceded that "there's a lot of obstacles" preventing an event in Croke Park, including - but not limited to - the time difference, a curfew for late-night events, and the financial demands of staging the event.
