NBC is pulling the plug on J.J. Abrams' spy series Undercovers.

The network is declining to pick up a full season of the show.

Undercovers will air three more episodes in the coming weeks. The addition three episodes in the can "will likely" air at some point, but there's no date set.

Undercovers broke the mold by casting two black leads as the show's main characters. But middling reviews and declining ratings made the show increasingly destined for the chopping block. Last night's airing only delivered 5.8 million viewers and a 1.3 adult demo rating.
