Kevin Love has been placed in the concussion protocol and will not play in Wednesday's game against the Hornets.
The Cavaliers have not released a timeline for how long Love will be out.
Jordan Mickey's elbow struck Love in the mouth and caused a front tooth subluxation, which means the tooth is loose but not displaced.
Love later showed some concussion-like symptoms at halftime and was held out of the second half for precautionary reasons.
