A dejected Larry Sanders sat on the trainer's table with his left ankle heavily wrapped.

It was the last place the Milwaukee Bucks center wanted to be Tuesday. A few minutes earlier the 6-foot-11 Sanders went up to block a shot and landed on Chandler Parsons' foot during a scrimmage, prematurely ending Sanders' on-court time in the USA Basketball national team minicamp.

Bucks general manager John Hammond, who returned to Las Vegas on a flight Tuesday morning, immediately went to check on the health of his player and stayed near Sanders' side while U.S. team trainers worked on him. The trainers determined the injury is a sprain, and Hammond said Sanders would undergo an X-ray and a magnetic resonance imaging exam.

"I want to play," Sanders said. "I felt like I was getting that second wind today.

"Unfortunate. I have to get an MRI. It looks like a sprain, though. It's pretty swollen."

U.S. coach Mike Krzyzewski came over to the trainer's table after the scrimmages ended to talk with Sanders. Several teammates also commiserated with Sanders, including New Orleans big man Anthony Davis.

The injury means Sanders will miss the final two days of the minicamp and the intrasquad game Thursday night at the Thomas & Mack Center.

"You definitely don't want anything like that to happen," said Detroit Pistons center Greg Monroe, one of the eight young big men in camp. "Especially in the summertime, in an arena like this when everybody is competing and trying to get a spot.

"It's unfortunate. I hope he's fine. I hope it's not that serious. Hopefully he'll be OK."

New U.S. assistant and Chicago Bulls coach Tom Thibodeau said Sanders has made great improvement.

"It's a whole group trying to learn a new system," Thibodeau said of the big man candidates. "In just watching his growth, in particular last year, and I'm very impressed with the way he (Sanders) has worked here.

"You can see that he's become a lot more confident. He's got great tools. And he's done a very, very good job thus far. He's got a special quality in the way he can block shots, defend and rebound, and that goes a long way toward winning."

Sanders is one of 28 players in the camp trying to impress Krzyzewski and the other members of the U.S. coaching staff. Only one of the players — New Orleans' Davis — was a member of the gold-medal winning squad at the 2012 London Olympics.
