The Hawks say Dedmon has been scheduled for a non-surgical procedure to address ongoing left ankle soreness. He is expected to be cleared for regular workouts following what the team says will be a short rehabilitation period.
Dedmon has started 52 of Atlanta's 64 games this season and averages 10.8 points and 7.5 rebounds.
The Hawks have six games left and are last in the Southeast Division. They hosted Eastern Conference-leading Milwaukee on Sunday.
