The UFC returns to Chicago on August 16 with a stacked UFC 319 event featuring one of the most highly anticipated middleweight title fights in years. South Africa's Dricus Du Plessis has taken the UFC by storm since arriving in the Octagon in 2020. After winning the UFC middleweight crown against Sean Strickland, he's continued to dominate with wins over Israel Adesanya and Strickland in their February rematch. But many believe his toughest test to date will be unbeaten challenger Khamzat Chimaev, whose list of UFC victories includes the names of Robert Whittaker, Kamaru Usman and Gilbert Burns.
