This is the live blog for Dricus du Plessis vs. Kamaru Usman, the middleweight main event for Saturday's UFC Oklahoma City card at Paycom Center in Oklahoma.

A former UFC middleweight champion, du Plessis has been out of action for nearly a year, last fighting in August when he dropped his title to Khamzat Chimaev in a defeat defined by du Plessis' inability to stop takedowns. Now, “DDP†is finally ready to get back in the cage and make another run at the belt, and he starts with one of the best wrestlers in welterweight history, Kamaru Usman.

Like du Plessis, Usman is a former champion, holding the UFC's welterweight title for enough years to nearly get into the conversation for divisional GOAT alongside Georges St-Pierre. An upset loss to Leon Edwards ended all that and started a tough slide for Usman, who rebounded with a win last summer over Joaquin Buckley in Atlanta. Now, Usman hopes to earn a title shot with a win over the former middleweight champion, either at middleweight or welterweight.
