According to a report from The Wrestling Observer Newsletter, one idea that has been pitched in WWE Creative is to once again reunite Bray Wyatt with Luke Harper and reform The Wyatt Family since both of their respective tag team partners are currently on the sidelines.
The report from The Observer notes that this is just an idea that has been pitched. Nothing is set in stone as of yet. If they go through with this plan though, it would seem logical that Erick Rowan would probably join them as well once he returns from his injury.
No word on which brand they would be on if WWE does end up going in this direction with them.
