Randy Brown has stepped down as assistant coach of the Chicago Bulls.

Jim Boylen had asked Brown to take a lesser role on the staff.

“I’m disappointed Randy won’t be with us,” Boylen said. “He’s going to move on and we’re going to move on. We’ve got games to play and we’ve got players to develop. We’ve got a franchise to uphold. … The train is moving out, so we gotta get going.’’

Brown has been in basketball operations with the Bulls since 2011.
