Thunder reserve James Harden has not yet been cleared to play after suffering a concussion when he took an elbow to the head from the Lakers' Metta World Peace. Coach Scott Brooks said Harden would not play Tuesday night against Sacramento and was not expected to even be at the Chesapeake Energy Arena. Brooks said Harden would be re-evaluated before Oklahoma City plays its regular-season finale against Denver on Wednesday night. He would not say whether he would play Harden if doctors allow it or hold him out as a precaution.
