Ilia Topuria needed just one round to finish Charles Oliveira, knocking him out cold to capture the vacant lightweight title in the UFC 317 main event.

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.

A new champion will be crowned in the lightweight division at the conclusion of this bout between Charles Oliveira and Ilia Topuria on Saturday at UFC 317.
