Put Marcus Williams on the growing list of Nets who are suffering from injuries. The rookie point guard did not play last night against the Pistons after he showed up at the morning shootaround with stiffness and spasms in his back.

Williams said he first injured himself two weeks ago against the Bucks at the Meadowlands. It flared up again in Milwaukee on Saturday, when he played just nine minutes and spent the majority of his time on the bench with a hot pack.
