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:

• Regarding Undertaker returning at Battleground this weekend, the word going around is that it may have to do with WWE wanting a better subscriber number for the Network and it could be leading to a match at SummerSlam.

• Ryback is off the card at Battleground but The Miz vs. Big Show is expected to go on as planned, likely as a number one contender match to the Intercontinental title. They may add a third participant.

• Dean Ambrose will play a role at Battleground, though it's unclear exactly what he'll be doing.

• It looks like Lana may be off WWE television while Dolph Ziggler is gone to film a movie.
