Before Conor McGregor became one of Ultimate Fighting Championship's (UFC) biggest stars, wrecking everything inside the Octagon -- and getting rewarded for it, too -- "Notorious" was trying to climb the ranks in the European regional circuit.
On the heels of his biggest fight against Chad Mendes, which will take place at UFC 189 tomorrow night (Sat., July 11, 2015) in Las Vegas, Nevada, we invite you to take a look back at the Irishman's last defeat inside the cage. A defeat that came four years ago under the Cage Warriors Fighting Championship banner against fellow countrymen Joseph Duffy.
Since then, McGregor has racked up 13 straight victories (five in UFC) and hasn't looked back.
But, those ghosts may come back and haunt McGregor down the road, as Duffy signed a UFC contract last year, making a successful Octagon debut against Jake Lyndsey at UFC 185. If Joseph can rack up a few more wins and build up his "brand," perhaps the two men will cross paths once again.
This time on the biggest mixed martial arts (MMA) stage of them all.
For now, McGregor has bigger fish to fry, as he tries to claim his first-ever UFC title by becoming the only man other than Jose Aldo to defeat Mendes.
