Henry Cejudo defeated TJ Dillashaw by TKO in the first round to retain his UFC flyweight championship Saturday night at the Barclays Center in New York.
The stoppage came at the 32-second mark of the bout, tying it for the fifth-fastest knockout or TKO in a title fight in UFC history.
Cejudo (14-2) made his first defense of the flyweight belt he won in August by upsetting longtime division champion Demetrious Johnson.
Dillashaw (16-4), the UFC's bantamweight champion, agreed to come down a weight class in hopes of picking up a second belt. The only UFC fighters to hold two belts simultaneously are Conor McGregor, Daniel Cormier and Amanda Nunes.
