Vassilis Spanoulis, one of defending champion Panathinaikos's major offseason signings, will miss the team's upcoming series of exhibition games, including two in the United States against the Houston Rockets and San Antonio Spurs, after suffering an injury in training Monday.

The 25-year old guard, who returned to the Greens this season after playing for the Rockets last year, hurt his left calf, which will sideline him for the next two weeks.
