Arnold Allen reminded the featherweight division why he remains one of the UFC’s toughest matchups Saturday night, earning a dominant unanimous decision victory over Melquizael Costa in the main event of UFC Fight Night.
Coming into the matchup, Costa carried major momentum after his recent knockout victory over Dan Ige and entered the bout riding a six-fight winning streak. Many fans viewed the Brazilian as one of the division’s fastest-rising contenders.
Instead, Allen used experience, composure, and pressure to completely slow the hype train.
How did Arnold Allen defeat Melquizael Costa?
The fight started at a fast pace with both featherweights trading calf kicks early. Costa attempted to establish his usual unpredictable offense with spinning attacks and body kicks, but Allen immediately answered with forward pressure and cleaner boxing combinations.
One of the biggest moments of the opening round came when Allen timed Costa during an exchange and landed a heavy left hand that spun the Brazilian around before dragging him to the canvas.
The fight quickly turned into a grinding battle.
Costa had success during scrambles and briefly threatened with grappling exchanges, including moments where he worked toward Allen’s back. However, Allen constantly stayed calm under pressure and continued finding answers whenever Costa started building momentum.
As the fight moved into the middle rounds, Allen’s jab became one of the biggest weapons of the night. The British contender repeatedly snapped Costa’s head back while mixing in takedowns and strong top control.
Costa continued attacking Allen’s lead leg with calf kicks and occasionally landed aggressive combinations, but Allen consistently landed the cleaner punches while controlling the pace of the fight.
