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 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.

Ilia Topuria's return to the lightweight division hit the slightest of snags. The former featherweight champion was first to step to the scale Friday morning for the UFC 317 official weigh-ins and he looked confident he would hit the 155-pound limit with ease.
