Boston coach Doc Rivers said at the team's morning shootaround that Rondo will not play Tuesday night against the Cavaliers but could return to the lineup later this week. Rondo is traveling with the team. Boston hosts Toronto on Wednesday.
The Celtics have gone 4-2 without Rondo, who hasn't played since Jan. 18, when he fell and sprained his wrist. Tests have shown no structural damage.
Rivers said center Jermaine O'Neal will play against Cleveland. He has been out for a week with a bruised left knee.
