Sergio Pettis, a former champion in Bellator MMA and Resurrection Fighting Alliance, is set to face Mitchell McKee in the main event of the PFL Chicago at Wintrust Arena. At 32 years old, Pettis brings a wealth of experience to the cage, having competed in 32 professional bouts, compared to McKee's 10. His extensive career includes a successful 14-fight tenure in the Ultimate Fighting Championship, where he achieved a 9-5 record against top-tier opponents. Known for his striking prowess, Pettis has a reputation as a crafty point fighter, with 16 of his 25 wins coming by decision, but he also possesses knockout power, as demonstrated by his victories via spinning backfist and guillotine choke. This fight holds additional significance for Pettis, as it marks his first appearance since the passing of his mentor, Duke Roufus, which adds emotional weight to his performance. The bout is set for April 11 at 9 p.m. ET, and fans can watch it live on ESPN2.
