Spain beat them handily, even without much of a contribution from Pau Gasol as the superstar forward exited the game with a back problem after playing less than eight minutes.
A statement on the Spanish federation's website said: "The Catalan player has felt a twinge in his back after a fight for a rebound and the national team's medical staff have diagnosed an acute lumbago which is being treated by physios.
"The injury is not serious so the player is expected to recover and travel to Japan along with his team-mates next Tuesday."
