Jamie Mullarkey promised not to let his third UFC fight be decided by the judges, and he more than lived up to that with a 46-second finish. Mullarkey (13-4 MMA, 1-2 UFC) opened Saturday’s UFC 260 main card on pay-per-view at the UFC Apex in Las Vegas with a quick knockout of Khama Worthy (16-8 MMA, 2-2 UFC), putting him in the promotion’s win column for the first time. The lightweights opened the fight with striking exchanges, and before they could even get warmed up, Mullarkey planted a perfect shot across Worthy’s chin. Worthy face-planted into the canvas.
