NBC cancels ailing 'Trauma'

NBC has cancelled its struggling medical thriller Trauma.

Despite ordering an additional three episodes of the series earlier this week, the network has now announced that it will not pick up additional instalments beyond the original 13-episode order.

The series, which currently airs on Monday nights after a lead-in from Heroes, opened to 6.93m last month, but has since dropped to 5.77m.

NBC has also announced an order for an additional six episodes of Chuck, which will likely return to a Monday night slot.
