Horford, an All-Star last season, tore his left pectoral muscle in January and may miss the remainder of the regular season. He said Wednesday he has been cleared to begin rehabilitation. Collins sprained his left elbow Feb. 2 and could miss another two weeks.
The 36-year-old Dampier is averaging 1.8 rebounds in 5 minutes per game, playing behind Zaza Pachulia and Ivan Johnson at center.
