The episodes, which were originally slated to debut on Friday, Oct. 21, will now air on Oct. 28. Chuck kicks off the night at 8/7c followed by Grimm at 9/8c.
Because the network's Thursday night comedy block had already planned four spooky episodes, NBC chose to air two days of Halloween-themed programming.
