Fight Nights Global will host BetCity Fight Nights 138 on June 6 in St. Petersburg, Russia, with promoter Kamil Gadzhiev confirming two welterweight Grand Prix bouts for the card.

Former Bellator welterweight champion Andrey Korreshkov is set to face Brazilian veteran Gleison Tibau in the first of the two announced matchups. Tibau, 42, brings a career record of 33-14 and trains out of American Top Team. The southpaw stands five-foot-ten with a 71-inch reach and has built a reputation as a relentless grappler, averaging over four takedowns per 15 minutes throughout his career.
The second Grand Prix bout pairs Sergey Romanov against Andre Muniz, the Brazilian known as "Sergipano." Muniz carries a record of 24-8 and competes out of Tata Fight Team Montes Claros. The 36-year-old southpaw stands six-foot-one with a 78-inch reach and is a dangerous all-around threat, landing strikes at a 48 percent accuracy rate while also averaging nearly four takedowns and more than one submission attempt per 15 minutes.

Why it matters
- Both bouts are part of a welterweight Grand Prix tournament, meaning the results will carry direct progression stakes beyond a single fight's outcome
- Tibau's grappling-heavy style sets up an intriguing contrast against Korreshkov's championship pedigree from his Bellator run
- Muniz's combination of striking accuracy and submission threat makes him a multi-dimensional test for Romanov at 170 pounds
- Further details on the tournament bracket and the remainder of the June 6 card have not yet been announced
