Rumor Roundup (April 4, 2017): Undertaker retirement, WWE roster shake-up, NXT call-ups, Gronk, 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:

• There are no plans for a more “official” statement of Undertaker’s retirement as he and WWE believe the segment in Orlando came off perfectly.
• Getting AJ Styles to Raw is still thought to be a top priority of the roster changes coming to Raw or SmackDown next week.
• A wave of NXT call-up is expected between now and the “Superstar Shake-up”, with Andrade “Cien” Almas and Tye Dillinger said to be joining The Revival and the expected arrival of Shinsuke Nakamura.
• Interestingly, there may have been a change in WWE thinking regarding Elias Samson, as The Drifter doesn’t seem to be a part of Raw or SmackDown plans right now.
• Rob Gronkowski did get approval from the New England Patriots’ management for his WrestleMania moment.
