Knicks G Calderon out 2-3 weeks
Calderon, who was acquired in a June trade from Dallas as part of the deal for Tyson Chandler, underwent an MRI in New York on Thursday. Coach Derek Fisher hopes to have Calderon back ''in a few weeks.''
Calderon sat out the final two preseason games after getting hurt on Oct. 20.
Fisher said he'll have Stoudemire play center with the second unit.
