The vacant UFC lightweight championship is up for grabs at UFC 317, with Ilia Topuria vs. Charles Oliveira, with the flyweight title on the line in the co-main.

Although Topuria has fought at lightweight in the past, this move up seemingly is a full commitment, and the differences in his frame could be spotted when he stepped on the scale at 155 pounds. There was a brief moment of confusion when the commission representative announced Topuria at 155.

The UFC 317 fight between Ilia Topuria and Charles Oliveira will be available through pay-per-view in the US on ESPN+. ESPN+ subscribers can opt to add it on to their monthly plan ( click here to see how ), and it's a $79.99 add-on to the monthly subscription.
