US guard Gilbert Arenas has been ruled out of the World Basketball Championship with a strained groin.
Arenas will be missed but the USA have other stars
The Washington Wizards player had been in contention to make the final squad of 12 alongside fellow NBA stars LeBron James, Carmelo Anthony and Dwayne Wade.
But he suffered the injury during a team practice session in South Korea.
"It's an unfortunate situation but he is not going to be able to continue on. We know Gilbert is disappointed," said USA basketball boss Jerry Colangelo.
"We're concerned because he has had a history regarding groin pulls. This is a precautionary move but it is important that he return home and get treatment."
USA head coach Mike Krzyzewski must now cut only one player from the 13 remaining to complete his roster for the tournament, which starts in Japan on Saturday.
