Spencer Hawes underwent an MRI on his lower back and left Achilles tendon while Elton Brand, who did not play in the Sixers' win over the Lakers on Monday, might miss his second game in a row because of a sprained thumb.

"He's a little sore," Sixers coach Doug Collins said of Hawes on Tuesday during the team's practice at the Philadelphia College of Osteopathic Medicine.

"His Achilles is sore again, and that's what I was worried about," Collins said. "I was worried about wear and tear. You knew looking at this season there were going to be a ton of injuries and how you were going to be able to survive them and how much depth you had was going to be important."

Brand said Tuesday that he's aiming to play against the Spurs.

"It's feeling better," said Brand, who did some catch-and-shoot drills. "It's better today, much better today. I'll get treatment again, and we'll see game time."
