NBC has effectively canceled Trauma opting not to give it a full season pick-up. The current plan is that the original order of 13 episodes will complete production and air, but no additional episodes will be ordered.
The move comes as no surprise, especially on the heels of a full season pick-up for Mercy.
This increases the odds of an early return for Chuck, likely in January. The Trauma news comes on the heels of NBC ordering six additional episodes of Chuck, which was originally scheduled to return in March. I’d look for its January return on Mondays at 8pm and for NBC to move Heroes to the 9pm time slot, just like last year.
