Yoo Su-young submits unbeaten prospect in UFC Edmonton return

Yoo Su-young, nicknamed "Yoo Jiu-jitsu," returned to the UFC after seven months away and handed an unbeaten prospect his first professional loss.

Yoo submitted Cody Kovanchek of Canada via kimura (low-ki lock) at 4 minutes and 19 seconds of the third round in a bantamweight bout at UFC Edmonton in Edmonton, Alberta, Canada, on Sunday (Korean Standard Time).

Kovanchek had gone 9-0 in professional MMA heading into the fight. Yoo handed him his first career defeat, reaffirming his own standing in the division.

Yoo seized control early with aggressive takedowns, dragging Kovanchek to the mat and securing top position before maintaining constant pressure to dictate the pace of the fight.

The decisive moment came in the third round, when Yoo trapped Kovanchek's arm during a ground exchange and locked in the kimura. Kovanchek tapped out, ending the contest.

The victory came roughly seven months after Yoo suffered his first UFC loss, to Elijah Smith in March. He bounced back in Sunday's bout.

It was also the first time Yoo had finished an opponent on the UFC stage. Long regarded as a grappling specialist, he converted his signature skill set into a finish.
