Arman Tsarukyan has confirmed he is serving as the official backup for the Ilia Topuria versus Justin Gaethje bout at UFC White House. Tsarukyan will be on standby should either fighter be unable to compete.
Arman Tsarukyan has confirmed he will serve as the official backup fighter for the lightweight title bout between Ilia Topuria and Justin Gaethje at UFC White House, scheduled for June 14, 2026. Tsarukyan will step in should either man be forced out of the contest before fight night.
Tsarukyan enters the standby role as the top-ranked lightweight contender, carrying a record of 23-3-0. The 29-year-old Russian, who trains out of American Top Team, stands five-foot-seven with a notably long seventy-two-inch reach. He is one of the division's most active wrestlers, averaging 3.26 takedowns per fifteen minutes, and connects on half of his significant strike attempts.
Topuria, fighting out of Spain under the Climent Club banner, holds a record of 17-1-0 and is currently ranked second in the lightweight division as well as first in the pound-for-pound standings. The 29-year-old stands five-foot-seven with a sixty-nine-inch reach and lands 4.81 significant strikes per minute at 48 percent accuracy, also adding nearly two takedowns per fifteen minutes to his offensive output.
Gaethje, the reigning lightweight champion, brings a record of 28-5-0 into the defense. The 37-year-old American from Genesis Training Center stands five-foot-eleven with a seventy-inch reach and leads all three fighters in striking volume, landing 6.48 significant strikes per minute at a sharp 58 percent accuracy rate.
Why it matters
- Tsarukyan is the division's No. 1 contender, meaning any replacement bout would carry immediate title implications.
- All three fighters are orthodox strikers with contrasting wrestling profiles, making stylistic continuity a factor if a swap occurs.
- The backup role keeps Tsarukyan in the championship picture regardless of whether he ultimately competes on June 14.
