Calvin Kattar looks to work his way back up the UFC men's featherweight rankings as he takes on rising prospect Arnold Allen in a main event at the UFC APEX in Las Vegas on Saturday (7 p.m. ET on ESPN+, with prelims at 4 p.m. ET on ESPN+).
Kattar, ranked No. 9 in ESPN's divisional rankings, is coming off a split-decision loss to Josh Emmett in June. Allen, ranked just ahead of Kattar in ESPN's rankings, is on a nine-fight win streak in UFC and has not lost a professional bout since June 2014. He earned a first-round knockout of Dan Hooker in his last appearance in the Octagon.
Brett Okamoto spoke to MMA coach Danny Castillo to get his perspective on the matchup. ESPN's betting experts Ian Parker and Reed Kuhn add their insights and analysis for the main event and other intriguing bets they like.
