Olivier Aubin-Mercier did what most fighters could not: He walked away at the top of his game and on his own terms.
The two-time Professional Fighters League lightweight champion announced his retirement from mixed martial arts in November, doing so with a pair of million-dollar pursues in tow. Aubin-Mercier made his debut with a 58-second submission of Guy Poulin at a Ringside MMA event on Oct. 21, 2011 and compiled a 21-5 record as a pro. All five of his losses resulted in decisions and took place across his 12 appearances in the Ultimate Fighting Championship between April 2014 and July 2019.
