Ross’ head bounced off the canvas just 17 seconds into Saturday’s prelim fight at T-Mobile Arena, putting Aguilar just behind Dustin Ortiz on the all-time leader for fastest knockouts at 125 pounds, according to the broadcast.
Check out the explosive finish below.
Aguilar, a submission specialist who earned the majority of his wins by tapout, stunned Ross when he faked a jab and came over the top with the looping punch. Ross was out from the second the punch connected.
The win put Aguilar back in the win column after a setback against Tatsuro Taira at UFC Vegas 68 in his octagon debut. The Contender Series vet stands at 9-2, while Ross suffered his second straight UFC loss and third overall after his Contender Series shot ended in a second-round knockout setback. Ross now stands at 13-8.
