NBC has decided that Chase doesn’t need to go on for so long this season. Executives at the Peacock Network have changed their mind about giving the series a full 22 episodes. The freshman drama series about a team of U.S. Marshals, and stars Kelli Giddish, Cole Hauser and Jesse Metcalfe,hasn’t pulled in the expected ratings. Studio insiders from both NBC and Warner Brothers say that the reduction of episodes from 22 to 18 does not mean that Chase has been canceled. It is still considered a full-season order for the series. Chase will be moved to Wednesdays beginning Jan. 12, 2011.
