WrestleMania 31 Rumor Roundup special: The Rock, Brock Lesnar vs. Roman Reigns, Seth Rollins, 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:

• Lots of speculation and rumors floating that The Rock will be at the show tonight and make an appearance in some capacity.

• Roman Reigns has become a betting favorite but the prevailing thought as of this writing, and this could change just hours before it happens, is that Brock Lesnar will retain the WWE world heavyweight title tonight.

• It looks likely that if Seth Rollins is cashing in the Money in the Bank briefcase it won't be tonight but tomorrow night on Raw.

• Rusev, Bray Wyatt, Undertaker, and Triple H are all getting big entrances, with Triple H apparently getting something really special.

• Sheamus is at the show and expected to be used in some way, though it's still unclear exactly what he'll be doing.
