A strained adductor muscle could keep Raptors' point guard Jose Calderon out of Spain's quarterfinal match against Lithuania on Friday, according to SportsNet.

"With respect to myself, my only concern is the small pull that I felt in the groin almost at the end of the game," Calderon said on his web site. "I feel a little soreness in the affected area, but until tomorrow I will not know the extent of the possible injury. We will have to wait a few hours to see how is the injury evolving, and depending on the results, we will know if I can play (Friday) or not."

Calderon was expected to undergo further treatment on Thursday.
