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 Observer is now reporting that Sting's debut may have been finalized in the days leading up to Survivor Series but it was in the plans for weeks.

Perhaps not surprisingly, WWE has considered the idea of doing a General Manager of the Week gimmick until they get something more concrete in place.

Big Show vs. Erick Rowan, Luke Harper vs. Dolph Ziggler, and Nikki Bella vs. AJ Lee are likely for TLC next month.

Rey Mysterio is expected back soon, although no date is set in stone. WWE is hoping to have most of its big name stars back by January so they're as close to a full roster as possible leading into Royal Rumble and the run up to WrestleMania 31.

Josh Matthews is expected to replace Mike Tenay as the lead announcer for TNA starting with its New York City tapings early next year, according to the Observer. It's part of the big makeover the company will undergo starting with its new deal.
