The USA Network website says in their listings that they will air an episode of NXT on Wednesday, December 13 at 7 PM ET. There’s no NXT scheduled this coming Wednesday and it’s most likely just for that week, as part of USA Network’s “WWE Week.” They’ll also air Tribute to the Troops on Thursday, December 14 (and Raw and SmackDown on Monday and Tuesday of that week).
There’s no word on if it’ll be a regular episode of NXT that will also air at 8 PM on WWE Network or a highlight show or something.
