The premieres of two NBC shows — one new drama and one popular program that is returning for its final season — have been pushed back a week, reports Deadline.com.

"Chuck" and "Grimm" will start a week later than originally planned, the story says. Both will now debut Friday, Oct. 28, as part of a two-night Halloween programming block that will start Oct. 27, the story says.

Thursday will feature Halloween-themed episodes of NBC’s comedies "Community," "Parks & Recreation," "The Office" and "Whitney," the piece adds.
