This is quite the week for Conor McGregor. The Dublin native will headline a UFC card in his hometown in just his third appearance for the world's premier mixed martial arts league when he faces the considerable challenge of Brazilian slugger Diego Brandao. Not only is this the biggest week and biggest fight of his career so far, McGregor will also have to find time to blow out a few birthday candles as today (Monday) also marks the 26th anniversary of his birth.

To mark this auspicious occasion, we figured we'd look into the Irishman's combat career thus far and cherry-pick 26 of his most notorious facts.
