Topuria (17-0 MMA, 9-0 UFC) made history at UFC 317, becoming the first undefeated fighter to win titles in two divisions. He accomplished the feat by knocking out former champion Charles Oliveira (35-11 MMA, 23-11 UFC) in the first round of the main event at T-Mobile Arena in Las Vegas, and only needed 2:27 to do it.

The Ultimate Fighting Championship wrapped up UFC 317 with a bang on Saturday, June 29, giving the crowd two straight finishes in the championship doubleheader.

Ilia Topuria's assent to unprecedented UFC history has been bulletproof. He did some amazing things prior to Saturday, but a first-round knockout of Charles Oliveira to become the first undefeated two-division champion in UFC history is easily his crowning achievement.
