NBC has reduced the order for freshman series Chase from 22 to 18 episodes, according to The Hollywood Reporter.

Chase and cult favorite Chuck were originally picked up for a full season in October, the day after NBC renewed its other first-year series Law & Order: Los Angeles, Outsourced and The Event. Chase started off reasonably well, premiering to 7.3 million viewers and a 2.5 rating in the adults 18-49 demo, but viewership has since fallen. The most recent new episode drew 6 million viewers and a 1.6 18-49 rating.

Not helping matters: Chase's lead-in, The Event, has also been on a downward ratings spiral.

NBC plans to move Chase to Wednesdays at 9/8c starting Jan. 12, where the Jerry Bruckheimer-produced drama will go up against two-hour episodes of American Idol.
