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.

International Fight Week 2025 in Las Vegas has arrived with UFC 317 and a pair of thrilling title fight matchups at lightweight and featherweight.
