Jason Collier, the Rockets second-year backup center, will continue his stay on the Injured Reserve for quite some time, according to Jonathan Feigen of the Houston Chronicle.  He was put on the IR before the season began with shinsplints.  As it turns out, it wasn't a phantom injury and Collier is slowly working his way back to health.  Still, trainer Keith Jones says it will be at least several weeks before he will be able to return to the active roster.
