Promoter Kamil Gadzhiev has confirmed two welterweight Grand Prix bouts for Betcity Fight Nights 138, scheduled for June 6 in St. Petersburg. Former Bellator welterweight champion Andrey Koreschkov will take on Brazilian veteran Gleison Tibau, while Sergey Romanov is set to face Andre Muniz on the same card.

Tibau, 42, brings a career record of 33 wins and 14 losses to the bout. The Brazilian southpaw, who trains out of American Top Team, stands five-foot-ten with a 71-inch reach. He has built his reputation largely on a wrestling-heavy game, averaging 4.08 takedowns per 15 minutes across his career, though his striking output sits at 1.95 significant strikes per minute with a 31 percent accuracy rate.
Muniz, known as "Sergipano," is a 36-year-old Brazilian southpaw who holds a record of 24 wins and 8 losses. Standing six-foot-one with a notably long 78-inch reach, he trains with Tata Fight Team Montes Claros. Muniz is a credible threat both on the feet and on the ground, connecting at a 48 percent striking accuracy rate while averaging 3.98 takedowns and 1.1 submission attempts per 15 minutes.

Why it matters
- Both bouts count toward the ongoing Betcity Fight Nights welterweight Grand Prix tournament, raising the stakes beyond a standard card.
- Koreschkov's Bellator title pedigree makes his clash with the seasoned Tibau a marquee Grand Prix matchup.
- Muniz's combination of reach, striking accuracy, and submission threat makes him a difficult stylistic puzzle for Romanov.
- The June 6 card in Russia's second-largest city stands to significantly shape the Grand Prix standings.
