'The Unit', 'Without A Trace' cancelled

CBS has cancelled veteran dramas The Unit and Without A Trace.

The shows, which ran for four and seven years respectively, are both noticeably absent from the network's 2009-10 lineup.

According to reports, CBS was torn between a renewal for Numb3rs and Without A Trace. The former was reportedly saved because it is less expensive to produce.

The network is expected to announce its full new season lineup later today.
