Tim Frazier started at point guard for the Wizards in Wall's place.
Wall ran into Channing Frye and took a tumble in the second half of Washington's 130-122 loss to the Cleveland Cavaliers on Friday. He stayed in the game but later said he should not have continued playing.
Wall underwent X-rays, which were negative, and left the arena with his arm in a sling.
Wall is averaging 20.5 points and 10.4 assists this season for the Wizards.
