Joseph Duffy finally gets his chance, on MMA’s biggest stage no less, to prove he’s more than just the last man to defeat Conor McGregor.

UFC officials today announced Duffy (12-1 MMA, 0-0 UFC), a recent UFC signee, will make his promotional bout against fellow lightweight Vagner Rocha (11-4 MMA, 1-3 UFC) at UFC 185.

Featuring a lightweight title fight between champ Anthony Pettis and challenger Rafael dos Anjos, UFC 185 takes place on March 14 at Dallas’ American Airlines Center. The main card airs on pay-per-view following prelims on FOX Sports 1 and UFC Fight Pass.

It’s not clear where Duffy vs. Rocha will be placed on the lineup.

Duffy began his pro MMA career in 2008, picking up back-to-back submission wins over current UFC fighters McGregor and Norman Parke. However, after suffering his first – and to date, only – MMA loss, he stepped out of the cage in favor of a pro boxing career. “Irish Joe” returned to MMA in 2014, picking up two stoppage wins under the Cage Warriors banner.

This past August, Duffy, who had a short stint on “The Ultimate Fighter 12,” told MMAjunkie Radio that witnessing McGregor’s quick rise certainly helped fuel his own desire for a return to the sport.

“Seeing how well those lads were getting on, it leaves some questions in your mind – ‘What if I stayed?'” Duffy told MMAjunkie Radio. “So I would definitely say that was a big part of it.”

Rocha, a former Bellator and Strikeforce fighter, is currently in his second UFC stint. The 32-year-old went 1-2 in his first UFC run, which included a submission win over Cody McKenzie. He then went 4-0 after his UFC release in 2012, but in his recent return fight, he suffered a submission loss to Jake Matthews in November.

With the addition to the card, UFC 185 now includes:

Champ Anthony Pettis vs. Rafael dos Anjos – for UFC lightweight title Champ Carla Esparza vs. Joanna Jedrzejczyk – for UFC strawweight title Roy Nelson vs. Alistair Overeem Matt Brown vs. Johny Hendricks Chris Cariaso vs. Henry Cejudo Ross Pearson vs. Sam Stout Ryan Benoit vs. Sergio Pettis Roger Narvaez vs. Elias Theodorou Daron Cruickshank vs. Beneil Dariush Joseph Duffy vs. Vagner Rocha
