CBS is pulling the freshman medical drama Three Rivers from Sunday nights effective immediately.
Starting December 6, the slot will be filled by repeats of an unspecified crime drama. The show is still in production and the network will complete all 13 episodes of the show's initial order.
No final decision has been made about its future beyond the 13, given the show's consistent sub-2.0 ratings. The network will probably at some point air the remaining episodes, but realistically the show is as good as canceled.
