Rondo sat the past three games for the Hawks, though he was medically cleared for Monday night's loss to the New York Knicks. He did not get on the court, leaving Brandon Goodwin to again serve as the backup point guard to Trae Young.
The Hawks said the 34-year-old Rondo will begin a period of rest and rehabilitation in an attempt to strengthen his knee.
He will be evaluated before the team leaves for a three-game West Coast trip that begins Jan. 13 at Phoenix.
Rondo has played only two of Atlanta's first seven games.
After winning his second NBA title last season with the Los Angeles Lakers, Rondo joined the rebuilding Hawks after agreeing to a two-year, $15 million contract. He is the team's oldest player.
