Chris Kaman suffered a back sprain during the Dallas Mavericks' first preseason practice.

Kaman has missed 69 games over the past two seasons.

“It was a really good practice,” coach Rick Carlisle said. “We had one casualty. Kaman went out with a sprained lower back. It’s not considered serious. So we’ll see how he’s doing for tonight and tomorrow and go from there. It’s not serious, but it was enough to keep him out of about half of what we did [in the morning].”

Elton Brand replaced Kaman at center in drills.

“I don’t know who’s going to start at center,” Carlisle said. “On paper, it looks like Kaman will be the starter, but we got a long way to go before we figure out what’s best for the team. Everything’s on the table.”
