Charles Oliveira vs. Arman Tsarukyan II Set for UFC 331 with BMF Title on Line

Charles Oliveira and Arman Tsarukyan are set to run it back, with the two lightweight contenders booked to headline UFC 331 in Los Angeles on September 19, 2026, this time with the BMF title at stake.

Oliveira, 36, enters the rematch as the No. 3-ranked lightweight in the world and sits at No. 11 in the pound-for-pound rankings. The Brazilian out of Chute Boxe Diego Lima carries a 37-11-0 record and remains one of the most dangerous finishers in the sport. Standing five-foot-ten with a 74-inch reach, "Do Bronxs" lands 3.35 significant strikes per minute at a remarkable 54 percent accuracy while also averaging 2.22 takedowns and 2.6 submission attempts per 15 minutes — a combination that has made him a nightmare for opponents on the feet and on the mat alike.

Tsarukyan, the 29-year-old Russian currently ranked No. 1 at lightweight, has built a compelling case as the division's most complete threat. Fighting out of American Top Team with a 23-3-0 record, "Ahalkalakets" stands five-foot-seven with a 72-inch reach and leads the pace game, averaging 3.85 significant strikes per minute. His wrestling adds another dimension — 3.26 takedowns per 15 minutes — making him one of the most well-rounded fighters in the weight class.

Why it matters

• The BMF title adds a marquee prize to what was already a high-stakes rematch between two of the best 155-pounders on the planet.
• Tsarukyan enters as the top-ranked lightweight, meaning a Oliveira victory would dramatically reshape the divisional picture.
• The stylistic contrast is stark — Oliveira's submission volume against Tsarukyan's elite grappling and striking output promises an action-heavy main event.
• A Los Angeles date gives UFC 331 one of the sport's larger market stages for what shapes up as a defining lightweight bout.
