Puerto Rican guard Carlos Arroyo hasn't played since the team's Group C opener against Russia on Saturday. He will not be back until at least Thursday, the final day of preliminary round play. Arroyo took a knee to his left quadriceps area, very close to his hip and had some internal bleeding. http://www.fiba.com/pages/eng/fc/news/lateNews/arti.asp?newsid=43875
