UFC Atlanta takes place this weekend with Kamaru Usman facing rising contender Joaquin Buckley in a highly anticipated welterweight clash. Despite being a former champion, Usman enters the bout as an underdog due to Buckley’s explosive style and recent win streak.

Francis Ngannou has faced a difficult stretch in recent months—both professionally and personally. From grieving the loss of his son to navigating uncertainty in his combat sports career, the former UFC heavyweight champion has been forced to reevaluate his path.

Though Ngannou's appearance at a UFC event does not mean that he is there to discuss business with the organization, this is the first time that the former champion has returned. UFC President Dana White was very outspoken about Ngannou's departure and comments on fighter pay, often responding with barbs that seemed very personal.
