Cheeks, who grew up on Chicago's South Side, was on Donovan's staff in Oklahoma City the past five seasons. The Bulls hired Donovan in September to replace the fired Jim Boylen.
A steady point guard who won a championship playing alongside Julius Erving and Moses Malone in Philadelphia, Cheeks spent most of his 15-year playing career with the 76ers. He was inducted into the Hall of Fame in 2018.
The Bulls also announced Saturday they have hired Josh Longstaff, John Bryant, Damian Cotter and Billy Schmidt as assistant coaches. Henry Domercant, Ronnie Burrell, Ty Abbott and Max Rothschild were added as player development coordinators.
