Spurs coach Gregg Popovich said that Manu Ginobili remains doubtful for Sunday’s playoff opener against Memphis and George Hill would likely start in his place if he can’t play.

“As things stand, he’s doubtful for the game,” Popovich said about Ginobili. “He’s working out and doing cardio with his legs.”

Ginobili suffered a strained right elbow in the opening minutes of the Spurs’ season-ending loss at Phoenix Wednesday night.

Popovich said he hasn’t talked to Ginobili about any pain he might be facing. Ginobili could be seen at the end of the media availability doing some curls in the team’s weight-lifting area with his injured right elbow covered with a padded protective sleeve.
