It seems as though everyone on the Spurs roster is taking their chance to take a game or two off. From the Spurs recent press release:
Marco Belinelli (back spasms) and Tiago Splitter (right calf contusion) are both questionable for tonight's Spurs-Bobcats game.
Additionally, Boris Diaw (food poisoning), Tim Duncan (rest) and Tony Parker (low back tightness) will all play in tonight's contest after missing the previous game at Brooklyn.
At least it's not all bad news. Duncan, Parker and Diaw are a nice consolation prize for having to go without Marco and Tiago.
