Andrey Koreshkov vs Gleison Tibau, Sergey Romanov vs Andre Muniz set for June 6

Promoter Kamil Gadzhiev has confirmed two welterweight bouts for BetCity Fight Nights 138, scheduled for June 6 in Saint Petersburg. Andrey Koreshkov will face Gleison Tibau, and Sergey Romanov will meet Andre Muniz, with both matchups forming part of a welterweight Grand Prix tournament structure.

Koreshkov, known as "Spartan," carries a 19-2-0 record into the contest and stands six feet tall at 35 years of age. He is one of the more active strikers in the division, averaging 2.84 significant strikes per minute with 39 percent accuracy, and his takedown rate of 4.8 per 15 minutes reflects genuine grappling pressure. He has no submission attempts on record, suggesting a style built around strikes and top control rather than finishing on the ground.

His opponent, Tibau, is a 42-year-old Brazilian southpaw out of American Top Team who holds a 33-14-0 record across a lengthy career. Standing five-foot-ten with a 71-inch reach, he averages 4.08 takedowns per 15 minutes and has long been regarded as a wrestling-heavy fighter, though his striking accuracy sits at 31 percent.

Muniz, nicknamed "Sergipano," is a 36-year-old Brazilian southpaw with a 24-8-0 record. At six-foot-one with a 78-inch reach, he brings notable physical tools to the welterweight bracket. He lands 2.08 significant strikes per minute at an impressive 48 percent accuracy and averages 3.98 takedowns per 15 minutes, adding 1.1 submission attempts per 15 minutes to round out a well-balanced offensive profile. His opponent Romanov was listed without verified data in the announcement.

Why it matters

• Two bouts feeding directly into a welterweight Grand Prix adds tournament stakes beyond a standard card
• Koreshkov and Tibau represent a striker-versus-wrestler dynamic with contrasting grappling philosophies
• Muniz's combination of accuracy, takedowns, and submission volume makes him a multi-dimensional threat in the bracket
