Mike Swick’s comeback bout at UFC 189 last week didn’t go as the veteran had hoped.

Far from his days as Mike “Quick” Swick, when he fought in the first season of The Ultimate Fighter, and later as a contender at welterweight, the 36 year old Swick looked sluggish and struggled do get any offense going against Alex Garcia — eventually losing a unanimous decision.

Today, Swick announced the bout — which was his first fight since 2012 — would be his last.

“I was healthy and injury free for the first time in eight years, but couldn’t put my game together,” he wrote in a message on his Instagram account. “There comes a time when every fighter realizes he is older and not what he use to be and I want to acknowledge this and stay true and honest to what I have always said, that I will leave when I know I am done. It’s a hard thing to do considering everyone wants to go out on top, unfortunately when your actually on top, you never wanna go out.”

“It’s unfair to the #UFC, the fans and to my family and friends for me to keep chasing this career while giving performances that I am not proud of,” he remarked.

In recent years, Swick focused his efforts on founding a martial arts academy in Phuket, Thailand. The project, which Swick describes as his “dream gym,” is an affiliate of American Kickboxing Academy in San Jose, CA.

He has chronicled the progress at the AKA Thailand YouTube page:
