Canadian MMA star and two-time PFL lightweight champion Olivier Aubin-Mercier has officially confirmed his retirement from the sport.

Five days removed from capturing his second successive PFL lightweight championship at the 2023 PFL World Championship event in Washington DC, Aubin-Mercier has considered his future, and posted to his Instagram page to announce his retirement.

“Feeling incredibly grateful today as I hang up my gloves,” he posted.

“I must give a massive shout-out to @pflmma. PFL believed in me. They recognized a fighter in a kid from Quebec who just wouldn’t quit. It has been an honor to step into the cage under their banner.

“As I move on from competition, I hope that the path I’ve trodden serves as an invitation to other Quebecois fighters. May you find in the PFL the same support, the same faith, and the same opportunities to showcase our Quebecois tenacity.

“To everyone behind the scenes who has been part of this journey – merci from the bottom of my heart. I had so much fun with you guys, even though I was probably a massive douchebag during those fight weeks. It’s been the fight of a lifetime. Here’s to the next round, whatever it may be!

“PFL, you’ve been the corner team everyone deserves. Merci pour tout.”

Aubin-Mercier calls time on his career on a perfect 10-fight win streak that included two million-dollar PFL lightweight championships. His career record reads 21 wins, five losses.
