Bet City Fight Nights 138 will feature two welterweight Grand Prix matchups when the Russian promotion heads to St. Petersburg on June 6, with promoter Kamil Gadzhiev announcing that Andrey Korshkov will meet Gleison Tibau and Sergey Romanov will take on Andre Muniz.
Tibau, 42, is a Brazilian veteran out of American Top Team who carries a 33-14 record into the bout. Fighting out of a southpaw stance at five-foot-ten with a 71-inch reach, the grappling-heavy fighter averages over four takedowns per fifteen minutes and has built his career on consistent wrestling pressure, though his striking accuracy sits at 31 percent.
Muniz, known as "Sergipano," enters at 36 years old with a 24-8 record for the Tata Fight Team Montes Claros. The Brazilian southpaw stands six-foot-one with a 78-inch reach of 198 cm and blends volume with real finishing ability, averaging nearly four takedowns and 1.1 submission attempts per fifteen minutes alongside a striking accuracy of 48 percent that suggests he is selective and effective on the feet.
Why it matters
- Both bouts are official Grand Prix tournament matches, meaning results directly shape the welterweight bracket for the Russian promotion
- Tibau and Muniz are experienced Brazilian veterans who bring legitimate grappling credentials, raising the competitive stakes for the Russian fighters opposite them
- Muniz's combination of submission volume and above-average striking accuracy makes him a stylistically complex opponent for Romanov to solve
