The Hawks have two more games remaining before the All-Star break, as they will host Orlando on Thursday before a five-day hiatus. Johnson, though, is an Eastern Conference reserve for Sunday's All-Star Game in Orlando.
Atlanta expects to have forward Marvin Williams back for Wednesday's game after he missed the 90-79 loss to the Bulls to attend the funeral of a family member. He is averaging 9.6 points and 5.4 rebounds in 28 games this season.
