Fight Nights Global will host two welterweight Grand Prix semifinals on June 6 as part of BetCity Fight Nights 138 in Saint Petersburg, with promotion president Kamil Gadzhiev confirming the pairings. Andrey Koreshkov meets Gleison Tibau in one matchup, while Sergey Romanov takes on Andre Muniz in the other, both bouts advancing the promotion's ongoing welterweight tournament.
Koreshkov, nicknamed "Spartan," carries an impressive 19-2-0 record into the semifinal. The 35-year-old stands six feet tall and has built a reputation as a high-volume striker, landing 2.84 significant strikes per minute at 39 percent accuracy. He also applies consistent grappling pressure, averaging 4.8 takedowns per 15 minutes, though he has never recorded a submission attempt in his career.
His opponent, 42-year-old Brazilian veteran Gleison Tibau, enters with a 33-14-0 record and brings decades of experience to Saint Petersburg. The southpaw from American Top Team stands five-foot-ten with a 71-inch reach and has long been a dangerous wrestler, averaging 4.08 takedowns per 15 minutes across his career. His striking output sits at 1.95 significant strikes per minute.
On the other side of the bracket, Andre Muniz — known as "Sergipano" — arrives with a 24-8-0 record and some of the sharper striking numbers in the tournament. The 36-year-old Brazilian southpaw stands six-foot-one with a 78-inch reach, lands 2.08 significant strikes per minute at 48 percent accuracy, and contributes on the mat with nearly four takedowns and 1.1 submission attempts per 15 minutes.
Why it matters
