NXT Star to be the possible mystery partner of Dean Ambrose and Roman Reigns, Eric Rowan Returning?

In a photo posted on WWE.com, which was later deleted, WWE may have inadvertently spoiled the six-man tag match at Night of Champions. As seen in the picture NXT‘s Baron Corbin is featured as the 3rd man alongside Dean Ambrose and Roman Reigns to take on the Wyatt Family.
Regarding an earlier rumor of former Wyatt member Eric Rowan returning, it seems rather unlikely now. Rowan has been out of action since June of this year after suffering a torn bicep and was said to recover in 4-6 months. A surprise return is always a possibility but more people are expecting him to be back around November.
