Flyweight Alex Perez picked up his first win in nearly four years Saturday at UFC Fight Night in Las Vegas, beating Matheus Nicolau with a second-round knockout.

Before dropping Nicolau with a right hook to end the fight at 2:16 of the second, Perez won Round 1 of the main event on all three scorecards. The win ended a three-fight losing streak for Perez, whose last win in June 2020 earned him a flyweight title shot against Deiveson Figueiredo.

Perez lost that match via first-round submission then dealt with years of injuries.

Perez is now 25-8-0. Nicolau is 19-5-1.

In the co-main event on Saturday, Bogdan Guskov beat Ryan Spann when the fight was stopped due to strikes at 3:16 of the second round.

It is the second straight stoppage win for the 31-year-old Guskov (16-3-0), who is looking to climb the rankings in the light heavyweight division. Spann fell to 21-10-0.

On the women's side, Karine Silva (19-4-0) defeated fellow Brazilian Ariane da Silva (17-9-0) by unanimous decision.
