Ilia Topuria is preparing for his UFC lightweight debut against Charles Oliveira on June 28, 2025, in the main event of UFC 317 at the T-Mobile Arena in Las Vegas, Nevada. This fight will determine the new lightweight champion after the division’s title was vacated, and it marks a significant step in Topuria’s career as he moves up from featherweight.
Background on Topuria’s Rise and Lightweight Ambitions
Earlier this year, Topuria announced he would relinquish the UFC featherweight championship to pursue opportunities in the crowded lightweight division. The undefeated fighter initially sought a superfight with Islam Makhachev, the then reigning lightweight champion, but Makhachev’s move to welterweight opened the door for Topuria to challenge Oliveira for the vacant title. This sets the stage for a high-stakes clash between two former champions at UFC 317.
Topuria’s Physical Growth and Preparation for Lightweight
Though Topuria has competed at 155 pounds before—most notably knocking out Jai Herbert at UFC London in 2022—he has never dedicated this much time and effort to solidify his presence at lightweight. He has spent approximately four months bulking up in preparation for this fight, committing to remain in the 155-pound category permanently. This dedicated training period has helped him develop a physique that fits well within the lightweight division.
During UFC 317’s media day, Topuria appeared noticeably larger, dispelling some fans’ doubts about his size for the division. At Friday’s early weigh-ins, he again looked physically imposing. While his exact fight weight against Oliveira remains unknown, this visible transformation suggests his readiness to compete with the division’s best.
UFC 317 Fight Card and Event Highlights
UFC 317, held during International Fight Week on June 28, 2025, features a championship doubleheader from the T-Mobile Arena. The main event will see Ilia Topuria battle Charles Oliveira for the vacant lightweight title in a five-round contest. Alongside this, the co-main event features Flyweight champion Alexandre Pantoja defending his 125-pound belt against top contender Kai Kara-France in a highly anticipated rematch.
The event also includes notable bouts such as Beneil Dariush facing Renato Moicano at lightweight, and a short-notice flyweight matchup between Brandon Royval and Joshua Van. UFC 317’s broadcast begins at 6:30 p.m. ET with early prelims on ESPN+, followed by prelims at 8 p.m. ET on ESPN and ESPN+, and the main pay-per-view card starting at 10 p.m. ET on ESPN+ PPV.
Fan Reactions and What to Watch for in the Main Event
Many fans have expressed skepticism regarding Topuria’s height in the lightweight division, yet his recent photos and weigh-in appearances suggest he has adapted well to the new weight class. His growth and transformation could prove crucial in overcoming the experienced Charles Oliveira, a former lightweight champion known as “do Bronx.” The bout carries significant implications for the division, determining who will claim the lightweight crown moving forward.
Looking Ahead: The Impact of Topuria’s Lightweight Transition
Ilia Topuria’s venture into the lightweight division represents a pivotal moment both in his career and for the UFC landscape. With Islam Makhachev’s move to welterweight creating an open path, this title fight could reshape the hierarchy at 155 pounds. A victory by Topuria would establish him not only as a dominant force in two divisions but also as a major contender in the UFC’s roster.
As UFC 317 unfolds, fans and analysts alike will watch closely to see if Topuria’s transformation and preparation translate into success against Oliveira’s proven championship experience.
