The Chicago Bulls have appointed Billy Donovan as head coach, the NBA franchise announced on Tuesday.
Terms of the contract were not disclosed but Donovan, 55, arrives after leaving the Oklahoma City Thunder following five seasons in charge at Chesapeake Energy Arena.
The Bulls had been looking for a new coach since dismissing Jim Boylen in August after finishing the coronavirus-hit 2019-20 season with a 22-43 record.
"I want to thank Jerry, Michael, Arturas and Marc for the opportunity to coach the Chicago Bulls," Donovan said.
"I also want to thank them for the time and effort they put into this hiring process. I'm excited to partner with Arturas [Karnisovas] as we work together on behalf of this historic franchise."
Donovan led the Thunder to the playoffs in each of his campaigns at the helm, but they bowed out in the first round for the fourth straight year in 2019-20.
After guiding the team to a 243-157 record, Donovan and the Thunder did not renew his contract.
The Bulls have not reached the playoffs since losing to the Boston Celtics in the Eastern Conference first round in 2016-17.
"We are very pleased to welcome Billy and his family to the Chicago Bulls. The success that he has sustained over the course of his coaching career puts him on a different level," said Bulls executive vice-president – basketball operations Karnisovas.
"We feel his ability to help his players reach their potential, both individually and collectively, will mesh well with our roster. Whether as a player or as a coach, he has won everywhere his career has taken him, and we hope that will continue here in Chicago."
