Fight Nights promoter Kamil Gadzhiev has confirmed two welterweight Grand Prix semi-final bouts for Betcity Fight Nights 138, scheduled for June 6 in St. Petersburg, Russia. Former Bellator welterweight champion Andrey Koreshkov will meet Brazilian veteran Gleison Tibau in one bracket, while Sergey Romanov faces Andre Muniz in the other.
Koreshkov, nicknamed "Spartan," carries an impressive 19-2-0 record into the tournament. The 35-year-old Russian stands six feet tall and is one of the more active strikers in the bracket, landing 2.84 significant strikes per minute at 39 percent accuracy. He also brings a strong grappling threat, averaging 4.8 takedowns per 15 minutes, and has no submission attempts on record, suggesting a ground-and-pound-focused wrestling game.

His opponent, Gleison Tibau, is a 42-year-old Brazilian veteran out of American Top Team with a 33-14-0 record. Standing five-foot-ten with a 71-inch reach, the southpaw is a seasoned grappler who averages 4.08 takedowns per 15 minutes, though his striking output sits at 1.95 significant strikes per minute with 31 percent accuracy.
In the other semi-final, Andre Muniz — known as "Sergipano" — enters at 24-8-0. The 36-year-old Brazilian southpaw is a well-rounded threat, standing six-foot-one with a 78-inch reach. He lands 2.08 significant strikes per minute at an efficient 48 percent accuracy and averages 3.98 takedowns per 15 minutes, supplemented by 1.1 submission attempts per 15 minutes.

Why it matters
- Koreshkov's Bellator pedigree makes him a credible favorite to advance, but Tibau's grappling experience presents a legitimate test
- Muniz's combination of striking accuracy and submission threat makes him a dangerous opponent for Romanov
- The two winners will meet to determine the Fight Nights welterweight Grand Prix champion
