Billy Donovan has resigned as head coach of the Chicago Bulls, ending his six-season tenure, after missing out on the play-offs.

The Bulls wanted to retain Donovan’s services despite parting company with vice president of basketball operations Arturas Karnisovas and general manager Marc Eversley on 6 April.

Donovan, 66, held an option in his contract for next season but has decided to step down to allow a new coach to rebuild.

“After a series of thoughtful and extensive discussions with ownership regarding the future of the organisation, I have decided to step away as the head coach of the Chicago Bulls, to allow the search process to unfold,” Donovan said.

“I believe it is in the best interest of the Bulls, to allow the new leader to build out the staff as they see fit.”
