Arman Tsarukyan has been officially announced as the backup fighter for the upcoming bout between Ilia Topuria and Justin Gaethje. This designation means Tsarukyan will be prepared to step in should either of the scheduled fighters be unable to compete. The fight is expected to take place at the White House event. Having an official backup ensures the main event remains secure even if last-minute issues arise with either competitor.
Arman Tsarukyan has been officially named the backup fighter for the lightweight title bout between champion Justin Gaethje and top contender Ilia Topuria, set to headline the White House event. Should either fighter be forced out before competition, Tsarukyan will be ready to step in and keep the main event intact.

Gaethje, known as "The Highlight," brings a 28-5 record into the fight as the reigning lightweight champion. The 37-year-old American, who trains out of Genesis Training Center, is one of the division's most prolific strikers, landing 6.48 significant strikes per minute at a 58 percent accuracy rate. Standing five-foot-eleven with a 70-inch reach, the Arizona native fights out of an orthodox stance and has built his reputation almost entirely on his stand-up game.
Topuria, nicknamed "El Matador," enters ranked second in the division and holds the number-one pound-for-pound spot in the world. The 29-year-old Spaniard carries a 17-1 record and trains out of Climent Club. He lands 4.81 significant strikes per minute and adds a consistent grappling threat, averaging nearly two takedowns and more than one submission attempt per 15 minutes of action.

Tsarukyan, ranked first in the lightweight division, is the logical insurance policy for this matchup. The 29-year-old Russian representing American Top Team holds a 23-3 record and is among the most active wrestlers in the weight class, averaging 3.26 takedowns per 15 minutes. He carries a 72-inch reach — the longest of the three fighters involved — and strikes at 50 percent accuracy.

Why it matters
- Tsarukyan is the division's top-ranked contender, so his involvement in any capacity carries serious title implications
- All three fighters are ranked inside the top two of the lightweight division, making this the deepest possible backup arrangement
- A Tsarukyan replacement scenario would represent a dramatically different stylistic challenge for whichever champion or challenger remains
