UFC lightweight veteran Evan Dunham says he’s going to retire after September’s UFC Fight Night 137 matchup against Francisco Trinaldo.

Dunham (18-7-1 MMA, 11-7-1 UFC), who made his octagon debut in February 2009, announced today that he intends to hang up his gloves after his matchup with Trinaldo (22-6 MMA, 12-5 UFC) in Brazil next month (via Instagram):

September 22 will be my last fight. I can retire from the sport that I love with my head held high. I know that I never held anything back while in the cage and September 22 will be no different. My goals and priorities have shifted throughout the years and I am ready to concentrate on building my gym, as well as any new opportunities that come my way.
I have gone toe 2 toe with many of the worlds best competitors and I am truly grateful for this. My passion for Jiu Jitsu will continue to be a driving force in my gym and at select Jiu Jitsu competitions.
I want to thank my family, friends and fans for all of your support throughout the years.

UFC Fight Night 137 takes place Sept. 22 at Ibirapuera Gymnasium in Sao Paulo. The card airs on FS1 following early prelims on UFC Fight Pass.

The 36-year-old, who resides out of Las Vegas, is currently winless in his past two bouts and hasn’t won since September 2016. Prior to that, though, Dunham was on a four-fight winning streak.

Dunham has fought many of the best at 155 pounds, including ex-champ Rafael dos Anjos, former title challenger Donald Cerrone and longtime contender Edson Barboza. He owns victories over Joe Lauzon, Ross Pearson, Gleison Tibau, Nik Lentz and Melvin Guillard.

Dunham’s 3:39:58 of fight time in UFC lightweight competition is ranked ninth most in UFC history. His 1,559 total strikes landed and 1,200 significant strikes landed are the most in divisional history.
