Arman Tsarukyan unlikely to serve as backup for Topuria vs Gaethje

Arman Tsarukyan appears set to step away from his listed backup duties for the upcoming lightweight title fight between Ilia Topuria and Justin Gaethje, with a prior commitment to RAF Wrestling on June 13 making his availability essentially impossible.

Tsarukyan, ranked number one in the lightweight division at 29 years old, carries a 23-3 record and represents one of the most complete fighters in the 155-pound weight class. The Russia-born American Top Team product stands five-foot-seven with a 72-inch reach and is particularly dangerous on the mat, averaging 3.26 takedowns per 15 minutes. His striking is equally disciplined, with a 50 percent accuracy rate across 3.85 significant strikes landed per minute.

The fight he was set to back up features the lightweight championship on the line. Justin Gaethje, the reigning champion, brings a 28-5 record into the bout at age 37. The Arizona product trains out of Genesis Training Center and is one of the most aggressive pressure fighters in the division, landing 6.48 significant strikes per minute at a 58 percent accuracy clip. The challenge comes from Spain's Ilia Topuria, ranked second in the division and first in the pound-for-pound rankings. The 29-year-old holds a 17-1 record and averages 4.81 significant strikes per minute, while also threatening with nearly two takedowns per 15 minutes and over one submission attempt in the same span.

Why it matters

• Tsarukyan is the top-ranked lightweight, so his absence as backup leaves the title fight without its most natural replacement fighter
• His scheduling conflict signals he may be positioning himself for a full camp ahead of his own lightweight title opportunity
• The Topuria vs Gaethje matchup carries significant pound-for-pound implications, with the number one P4P fighter challenging for a second divisional title
