The Atlanta Hawks learned this morning that an MRI has revealed that forward/center Obinna Ekezie has torn his right anterior cruciate ligament, it was announced by General Manager Billy Knight. The 6-9 free agent training camp invitee suffered the injury with less than seven minutes left in Thursday's game at Miami when he went up for a rebound and landed awkwardly on the floor. He did not return to action and is sidelined indefinitely.
