在费城举办的UFC 330赛事中，麦肯齐·德恩以一致判定的方式成功卫冕115磅草量级冠军[1]。三位裁判分别给出49-46、49-46、48-47的比分，德恩击败挑战者吉莉安·罗伯逊[1]。这是德恩在UFC 321赛事中获得空缺冠军头衔后的首次卫冕，目前其职业战绩为17胜5负[1]。
伊斯兰·马哈切夫将在同场赛事中挑战170磅冠军头衔[1]。现为28胜1负战绩的马哈切夫已保持16连胜，与UFC名人堂成员安德森·席尔瓦并列保有连胜纪录[1]。若其在本场比赛中获胜，将创造17连胜的新纪录[1]。
此外，现年40岁的轻量级老将埃德森·巴博萨在本赛事中落败，随后宣布退役[1]。巴博萨的UFC职业生涯始于2010年，其最后四场比赛均告失利[1]。UFC 330是费城举办的第三场编号卡赛事，同时也是该城市自2019年以来首次举办的UFC赛事[1]。

On the same card, Islam Makhachev entered his welterweight title challenge carrying a 28-1 record and an active winning streak of 16 consecutive victories [1].

The event marked Philadelphia's third numbered UFC card and the city's first since 2019 [1].

Barboza's final four UFC bouts all resulted in defeats [1].
