Fight Nights Global president Kamil Gadzhiev has confirmed three bouts for BetCity Fight Nights 138, scheduled for June 6 in Saint Petersburg. Headlining the welterweight Grand Prix portion of the card are two notable matchups: Andrey Koreshkov against Gleison Tibau, and Sergey Romanov against Andre Muniz.
Andrey Koreshkov, nicknamed "Spartan," carries one of the more impressive records in the welterweight division at 19-2-0. The 35-year-old stands six feet tall and is an aggressive, well-rounded fighter who lands 2.84 significant strikes per minute and averages 4.8 takedowns per 15 minutes — while recording zero submission attempts, suggesting a pure grappling-for-control approach rather than a finishing game on the ground.
His opponent, Gleison Tibau, is a 42-year-old Brazilian veteran out of American Top Team with a professional record of 33-14-0. A southpaw standing five-foot-ten with a 71-inch reach, Tibau has built his career around wrestling, averaging 4.08 takedowns per 15 minutes. His striking output sits at 1.95 significant strikes per minute at 31 percent accuracy.
The co-feature of the Grand Prix sees Sergey Romanov face Andre Muniz, nicknamed "Sergipano." The 36-year-old Brazilian southpaw holds a 24-8-0 record and trains out of Tata Fight Team Montes Claros. Standing six-foot-one with a 78-inch reach, Muniz brings a balanced offensive profile — 2.08 significant strikes per minute at 48 percent accuracy, combined with 3.98 takedowns per 15 minutes and 1.1 submission attempts per 15 minutes.
Why it matters
- Both Grand Prix bouts feature high-level welterweights with credible international resumes, raising the stakes of the Saint Petersburg card.
- Koreshkov's elite takedown volume against Tibau's own wrestling-heavy style sets up an intriguing grappling battle.
- Muniz's submission threat and Romanov's profile could produce one of the more technically complex fights of the evening.
- The tournament format means Grand Prix results will carry implications beyond a single night.
