Russian promoter Kamil Gadzhiev has confirmed two welterweight grand prix bouts for BetCity Fight Nights 138, scheduled for June 6 in St. Petersburg. Andrey Korreshkov meets Gleison Tibau in one quarter, while Sergey Romanov takes on Andre Muniz in the other, with both contests forming part of the promotion's ongoing welterweight tournament.

Gleison Tibau brings a wealth of experience to the matchup against Korreshkov. The 42-year-old Brazilian, who trains out of American Top Team, carries a 33-14-0 record and fights out of a southpaw stance. Standing five-foot-ten with a 71-inch reach, Tibau has long been a threat on the mat, averaging over four takedowns per 15 minutes across his career. His striking output sits at around 1.95 significant strikes per minute.
Andre Muniz, known as "Sergipano," enters his bout against Romanov at 36 years old with a 24-8-0 record. The Brazilian southpaw stands six-foot-one and carries a 78-inch reach, giving him considerable physical advantages in most welterweight matchups. Muniz averages 2.08 significant strikes per minute at a 48 percent accuracy rate, and he poses a consistent grappling threat, averaging nearly four takedowns and 1.1 submission attempts per 15 minutes.

Why it matters
- Both bouts feed directly into the welterweight grand prix, meaning winners advance in the tournament bracket
- Tibau's wrestling-heavy style sets up an intriguing contrast against Korreshkov's approach
- Muniz's combination of striking accuracy and submission volume makes him a multi-dimensional threat for Romanov
- The June 6 card in St. Petersburg shapes up as a significant night for the Russian promotion's flagship tournament
