Korshkov vs Tibau, Romanov vs Muniz announced for BetCity Fight Nights 138

BetCity Fight Nights 138 is taking shape, with promoter Kamil Gadzhiev confirming two welterweight Grand Prix matchups for the Saint Petersburg card on June 6. Andrey Korshkov will meet Gleison Tibau, and Sergey Romanov will face Andre Muniz, with both contests forming part of the organization's ongoing welterweight tournament.

Gleison Tibau, the 42-year-old Brazilian southpaw out of American Top Team, carries a professional record of 33-14. The five-foot-ten veteran has a 71-inch reach and has built much of his career around a strong grappling base, averaging 4.08 takedowns per 15 minutes. His striking output sits at 1.95 significant strikes landed per minute, though his accuracy of 31 percent reflects a volume-over-precision approach.

Andre Muniz, nicknamed "Sergipano," brings a 24-8 record into the bout against Romanov. The 36-year-old Brazilian stands six-foot-one with a 78-inch reach and trains out of Tata Fight Team Montes Claros. A southpaw with well-rounded offensive tools, Muniz lands 2.08 significant strikes per minute at an accuracy rate of 48 percent and adds consistent grappling pressure, averaging 3.98 takedowns per 15 minutes alongside 1.1 submission attempts per 15 minutes.

Why it matters

• Both bouts carry Grand Prix implications, meaning wins and losses will directly shape the welterweight tournament bracket
• Tibau's takedown volume sets up a potential wrestling-heavy contest against Korshkov
• Muniz's combination of striking accuracy and submission threat makes him a multi-dimensional puzzle for Romanov
• The June 6 Saint Petersburg card now has two confirmed tournament bouts anchoring the lineup
