Chimaev (14-0 MMA, 8-0 UFC) sought help from strength and conditioning coach Calavitta to address the criticism surrounding his cardio as he prepares for his first championship fight. Chimaev challenges Dricus Du Plessis (23-2 MMA, 9-0 UFC) for the middleweight title in Saturday's main event (pay-per-view, ESPN, ESPN+) at United Center in Chicago.

At the post-weigh-in press conference, Dustin Poirier, Michael Chiesa, Anthony Smith, and Chael Sonnen sat down to break down the UFC 319 card and of course, most of the talk centered on the main event between Dricus du Plessis and Khamzat Chimaev.

UFC middleweight champion Dricus du Plessis will battle his opponent as well as what figures to be a hostile crowd when he defends his title against Khamzat Chimaev in the main event of UFC 319 at the United Center on Saturday.
