Joaquin Buckley's hop flipping back kick-stop victory against Impa Kasanganay might be the year's knockout, but the best KO ever.

The 26-year-old American fought Kasanganay during the ongoing UFC "Battle Island" festival at the Yas Island Flash Forum, Abu Dhabi, on Saturday, October 10.

Kasanganay seemed to have power halfway through the middleweight bout 's second round when he grabbed one of Buckley's kicks and had his opponent's foot in his hand palm.

But, displaying incredible creativity, Buckley transitioned into a back-kick leap.

The maneuver took Kasanganay by surprise, and he actually didn't even know what had happened until he woken up later, as the strike left him on the floor.

Those viewing Octagonside, behind-closed-doors and sanitized venue, were clearly in awe, viewing open-mouthed and in the air with their weapons.

"I saw that he still had my ankles, I was still able to balance my foot, so I just spun and kicked," Buckley said after the game.

"I shot and I fired, and it got the outcome we wanted. I know I landed flush, but I didn't know if I knocked him out until he locked up and I said it was done.

"The only thing that was new was he kept my shoulder, but I'm practicing it all the time."

Buckley was given a $50,000 performance-related incentive check for the finish.

Official UFC social media channel credited Buckley's finish as "the most impressive KO in UFC history."

It'll actually repeat indefinitely.
