It’s not known for sure if Piston’s newly acquired point guard Jose Calderon will play tonight when Detroit takes on Cleveland at the Palace. The 31-year old, eight year veteran arrived in Detroit Thursday following the Wednesday 3-team trade that brought Calderon to the Pistons from Toronto with Tayshaun Prince and Austin Daye leaving Motown and headed for Memphis. The 17-and-29 Pistons have dropped two straight games and four of five but they also have won their last four meetings with the Cavaliers.
