Korshkov vs Tibau and Romanov vs Muniz set for BetCity Fight Nights 138

Promotion chief Kamil Gadzhiev has confirmed two welterweight Grand Prix bouts for BetCity Fight Nights 138, scheduled for June 6 in Saint Petersburg, Russia. Andrey Korshkov meets Gleison Tibau in one contest, while Sergey Romanov takes on Andre Muniz in the other, with both fights forming part of the promotion's welterweight Grand Prix tournament.

Tibau, a 42-year-old Brazilian southpaw out of American Top Team, carries a professional record of 33 wins and 14 losses. Standing five-foot-ten with a 71-inch reach, the veteran is a persistent grappler, averaging more than four takedowns per fifteen minutes across his career. His striking output sits at 1.95 significant strikes per minute, with a 31 percent accuracy rate.

Muniz, who competes under the nickname Sergipano, is a 36-year-old Brazilian also fighting out of a southpaw stance. He holds a 24-8 record and brings considerably longer dimensions to the cage, standing six-foot-one with a 78-inch reach. Representing Tata Fight Team Montes Claros, Muniz generates 2.08 significant strikes per minute at a 48 percent accuracy rate and averages nearly four takedowns per fifteen minutes, complemented by 1.1 submission attempts in the same window.

Why it matters

• Both bouts carry Grand Prix tournament weight, meaning the outcomes will directly shape the welterweight bracket at BetCity Fight Nights.
• Tibau's elite takedown volume sets up a striking-versus-wrestling dynamic against Korshkov.
• Muniz's combination of accuracy, takedown output, and submission threat makes him a multi-dimensional danger for Romanov.
• The June 6 card in Saint Petersburg positions BetCity Fight Nights 138 as a pivotal night for the promotion's welterweight division.
