USA Basketball says Lamar Odom won't try to earn an Olympic roster spot, leaving the Americans with 15 players for 12 spots.

Odom informed USA Basketball chairman Jerry Colangelo and coach Mike Krzyzewski that he was unable to play this summer. He had previously been expected to take part in training camp this week despite a difficult season in which he and the Dallas Mavericks parted ways early.

With the Americans lacking size up front, Odom's departure could strengthen new Clippers teammate Blake Griffin's hopes of making the team, or perhaps open the door for Memphis' Rudy Gay.

The remaining players that are expected to report to camp Thursday in Las Vegas are: LeBron James, Kobe Bryant, Carmelo Anthony, Kevin Durant, Deron Williams, Chris Paul, Tyson Chandler, Kevin Love, Russell Westbrook, Andre Iguodala, James Harden, Eric Gordon and rookie Anthony Davis. Davis sprained his ankle Saturday and his status is not yet known.
