Johnny Walker’s brutal heavyweight debut KO earns UFC 332 bonus

Four UFC 332 fighters earned $100,000 Performance of the Night bonuses following Saturday's event at the Delta Center, each securing their victories with devastating first-round finishes.

Johnny Walker marked his heavyweight debut with a brutal knockout of Mick Parkin at 3:35 of the opening round. The Brazilian established a Thai clinch before driving a left knee directly into Parkin's jaw, leaving the English fighter unconscious on the canvas.

Damian Pinas continued his rise through the middleweight ranks with a lightning-quick finish of Andrey Pulyaev. Just 75 seconds into the bout, Pinas landed a flush right uppercut that sent Pulyaev crashing to the mat and improved his record to 11-1. Following his victory, Pinas immediately called for a matchup against a top-10 opponent.

Imanol Rodriguez remained unbeaten at 8-0 after stopping Alden Coria in the first round. Rodriguez used his superior hand speed early before connecting with a perfectly-timed front kick to the body that dropped Coria and prompted referee stoppage at 3:11.

Roman Kopylov derailed Ateba Abega Gautier's momentum with a first-round knockout at 3:12. Kopylov stunned Gautier with a straight left hand before finishing the Cameroonian with a barrage of hammerfists after he hit the canvas.
