Jesus Aguilar opened UFC 290 at T-Mobile Arena in Las Vegas by setting the bar very high, and Shannon Ross very low.
The Mexican flyweight delivered a brutal one-punch knockout 17 seconds into the second fight on the card. It was the second-fastest KO in UFC flyweight history and the first knockout victory of Aguilar's professional career.
There's really no way to dress up the fight. Ross threw out a half-hearted kick to the body, then Aguilar responded with a left jab, then connected on a hard right that put his Australian opponent out cold.
