Injuries mount for Team USA with the latest being Los Angeles Clippers forward Blake Griffin, who is out of the London Games with a meniscus tear in his left knee.

According to The Los Angeles Times, Griffin, who flew back to L.A. to visit with team doctors, will likely have to have arthroscopic surgery early next.

"We're relieved that this does not affect Blake's ability to be ready in time for training camp," Clippers coach Vinny Del Negro said in a statement. "Missing out on the Olympic experience will be tough for him to take. We're glad we can get this fixed now and take advantage of the available time for him to fully recover."

A video of Wednesday's practice revealed Griffin had a collision with U.S select team point guard John Wall of the Washington Wizards. Driving to the basket, Wall-with his left leg-clipped Griffin's left knee. Late in the practice, a trainer placed a soft brace on Griffin's left knee.

USA Basketball chairman Jerry Colangelo said there seemed to had been no indication anything was wrong after Wednesday's practice, but Griffin awoke Thursday with swelling and discomfort.

With Griffin unavailable for Thursday's practice and a scrimmage game looming against the Dominican Republic team, Colangelo phoned forward Anthony Davis, the No.1 overall pick of the New Orleans Hornets in June, and asked him to re-join the team for practice. Davis was one of the finalists to make the 12-man Olympic roster, but a sprained ankle prevented him from practicing with the team last week.

Davis is now expected to join Team USA in their chase for another gold medal and will serve as a nice addition to the team with his 6-foot-10 frame adding more size to the paint.

Davis is not the typical big-man, with his agile footwork and intimidating shot blocking ability, it will be interesting to see how he fairs in the international game.

The rookie got his first taste of playing for Olympic team Thursday night in a 113-59 exhibition victory over the Dominican Republic.
