Assistant Tony Brown ran the team in his place.
Dunleavy is in his seventh season as Clippers coach and his second in the dual role of general manager. He has the third-longest tenure among current NBA coaches behind Utah's Jerry Sloan and San Antonio's Gregg Popovich.
The last time Dunleavy missed a game was Nov. 27, 2008, when he was in Dallas for the funeral of his father-in-law. Kim Hughes filled in for him on that occasion.
