Smith, Horford return for Atlanta in Game 4

BOSTON (AP) Center Josh Smith and forward Al Horford are back for Game 4 of the Atlanta Hawks' first-round playoff series against the Boston Celtics.

Smith missed Game 3 with a strained tendon in his left knee but was in the starting lineup. Horford, who had not played since Jan. 11 with a torn left pectoral muscle, came off the bench.

The Celtics had Ray Allen back for the second straight game after he missed almost a month with bone spurs in his right ankle. Guard Avery Bradley was in the starting lineup one game after dislocating his shoulder.
