Shamil Abdurakhimov defeats Marcin Tybura in the second round TKO
Abdurakhimov grabbed Tybura with a left hook at the temple that made him wobble, then followed Tybura across the octagon and launched a series of strokes as his opponent sank against the cage, until the referee jumps to 3:15 of the 2nd inning.
The heavyweights engaged in a standing battle throughout the match. The Russian Abdurakhimov (20-4) landed more regularly until Tybura (17-5) began to time his counter-batters. The end came when this hook caught Tybura flush with his right temple and his balance left him. It was the third consecutive victory of Abdurakhimov.
Michal Oleksiejczuk defeats Gadzhimurad Antigulov by the first round KO
Oleksiejczuk turned around because his last fight in February lasted barely a minute and a half. This time, it took him even less time to get the knockout, catching the aggressive Antigulov and releasing him three times in a bout that lasted only 44 seconds.
Oleksiejczuk (14-2), a 24-year-old Pole, is undefeated in his last 12 fights, while Antigulov (20-6) lost his second straight game after a run of 14 wins.
Mustafaev, who had not fought since 2016 because of an arm injury, did not have the chance to test this arm, as he quickly pushed Fiziev back from a stroke step back to cover the Kazakhstan fighter and finish it just 1:26 in the fight.
It was the first defeat in MMA for the Muay Thai specialist, Fiziev (6-1), hit by the first kick by Mustafaev, then reversed and stunned by the second. Mustafaev (15-2), from Dagestan, finished the job with a flurry of punches on the canvas.
