Coach Mike Budenholzer said Korver had a procedure performed in Los Angeles on Monday and will re-evaluated after games this week against Sacramento, Golden State and Oklahoma City.
Korver went out after taking an offensive foul from Ed Davis in the first half Sunday.
Korver's injury was the latest blow on a West Coast road trip that has already claimed backup forward Mike Scott. He is expected to miss to six weeks because of a broken toe on his left foot.
The Hawks are hoping to soon get back forward Thabo Sefolosha, who has been out since Jan. 30 with a strained right calf.
