Scoop! CSI Finds Grissom's "Replacement"

As I reported in this week's Ask Ausiello, CSI has tapped Tony winner Liev Schreiber to fill the temporary void left by William Petersen. Schreiber will play a seasoned CSI who joins the veteran team at the Las Vegas Crime Lab. He'll debut in Episode 12, slated to air in January.In other casting prattle, Desperate Housewives has found a new plaything for Eva Longoria. Sources confirm that Mark Deklin, most recently seen as Dr. Shaw on Fox's Justice, is joining the cast for at least three episodes as a love interest for Gabrielle. He first shows up on Nov. 26.
