The worst injury may be to Thabo Sefolosha, who the Hawks said could miss up to two months with a right calf injury. DeMarre Carroll and Shelvin Mack are also out with injuries against the 76ers.
Carroll was also held out of Friday night's 105-99 win over Portland with a left Achilles strain. Sefolosha started for him but lasted only two minutes before leaving with a calf strain.
Tests confirmed the strain and he is expected to miss six to eight weeks.
Mack, a backup point guard who has a left calf strain, missed his sixth straight game.
The winning streak has lifted the Hawks to the NBA's best record at 39-8.
