Derrick Lewis, a prominent figure in the UFC heavyweight division, has withdrawn from his scheduled fight against Jhonata Diniz at UFC Edmonton due to a non-weight-cut-related medical issue, marking the third time he has had to pull out of a fight on short notice. The bout's cancellation leaves the event with 13 fights, and a women's flyweight match has been promoted to the main card as a result. Lewis, known for his knockout power, was looking to build on his recent victory over Rodrigo Nascimento but now faces uncertainty regarding his next opponent. Despite this setback, speculation about a matchup with Alexander Romanov persists. UFC Edmonton will proceed with Brandon Moreno and Amir Albazi headlining the event.
