Rumor Roundup (Dec. 4, 2015): Vince McMahon on NXT, Alberto Del Rio plans, Sami Zayn return, more!

Speculating on the rumors surrounding pro wrestling is a favored pastime of many fans, perhaps second only to actually watching the matches. In this daily column, we take a look at the latest rumors being churned out by the pro wrestling rumor mill.

Important reminder: Rumors are just that -- rumors. None of this has been confirmed as legitimate news or fact, it's just circulating around the pro wrestling rumor mill. Remember, take it all with a grain of salt.

Rumors for the Day:

• The NXT lines on Raw this week apparently came from Vince McMahon and the idea is to differentiate between the two promotions.

• Alberto Del Rio and Zeb Colter won't be continuing as a partnership much longer, according to the Observer. They have plans for Del Rio in 2016 that don't include the two together.

• The expectation is that Sami Zayn will wrestle on the NXT tour of the UK, although that isn't expected to include the Takeover: London show.

• WWE is interested in bringing Jay Lethal in for NXT, according to the latest Wrestling Observer Newsletter, and his contract with Ring of Honor is apparently up soon.

• Although the Observer reported Melina Perez and Lucha Underground parted ways over her attitude, Pro Wrestling Sheet is reporting that's not the case and her appearance was only a one-time thing and the two sides couldn't come to an agreement on more dates.
