Washington Wizards point guard John Wall suffered a left shoulder sprain in Friday night's loss, and his status for Sunday's game is uncertain.
"It's on fire right now," Wall said about his shoulder. "It was like my arm went dead."
Wall ran into Channing Frye and took a tumble in the second half of Washington's 130-122 loss to the Cleveland Cavaliers. He stayed in the game, but later said he should not have kept playing.
Wall underwent X-rays, which were negative, and left the arena with his arm in a sling.
He finished with 13 points, shooting 4-for-13 from the field and 5-for-12 on free throws, and handed out 15 assists.
The Wizards play the Raptors in Toronto on Sunday before returning to Washington for a four-game homestand.
