Spurs coach Gregg Popovich isn't concerned about how slowly Manu Ginobili's ankle in healing just yet, but he could start worrying at the end of the week.

"This coming Thursday will be four weeks since he's off the crutches," Popovich said Saturday. "At that point, we hope that he's on the floor working out. If he's not, we'll be concerned."

Ginobili is battling a stress reaction in his right ankle, and has missed the team's last 14 games.

"I keep saying a week or two," Popovich said. "It's like the stimulus package ? pretty soon, it's going to start having an effect."
