Tyreke Evans left Friday's game late in the fourth quarter as the Milwaukee Bucks rallied for a 114-108 double-overtime win.
Evans sustained a concussion in a fall and went to the locker room with 24.4 seconds left in regulation and the Kings ahead 91-89.
Evans also had lacerated gums and a chipped tooth, and doctors will check to see whether he has a broken jaw. Evans will not travel with the team to Los Angeles for Sunday afternoon's game against the Clippers.
