to get 2nd opinion on his back.
From Josh Robbins of the Orlando Sentinel:
Dwight Howard has gone to Los Angeles with a member of the Orlando Magic’s medical staff to get a second opinion on his aching back. Howard will not play when the Magic host the Atlanta Hawks tonight, and he is not expected to play in the Magic’s road game Sunday against the Cleveland Cavaliers or the Magic’s home game Monday versus the Philadelphia 76ers.
Doctor said Dwight needs a backiotomy.
