Here's an interesting little nugget discovered by June M. Williams when perusing the WWE Facebook page: The company is advertising current WWE Champion The Rock for its Extreme Rules pay-per-view (PPV) event on Sun., May 19, 2013, at the Scottrade Center in St. Louis, Missouri.

WWE returns to St. Louis on Sunday, May 19 at 6:30pm when EXTREME RULES is broadcast to the world from St. Louis' Scottrade Center for the first time ever! See WWE Champion The Rock, John Cena, CM Punk, St. Louis' own Randy Orton, The Celtic Warrior Sheamus and many more!

The advertisement is for tickets, which go on sale tomorrow morning at 10 a.m. ET and can be purchased here.

Naturally, this brings into question both the plans for Rock and the value of advertising. The card is always subject to change and nothing is ever set in stone but you don't want to ever outright lie to your fanbase to get them to purchase tickets knowing full well someone you promised would be there would not.

You know, kind of how TNA advertised Jeff Hardy for the tour of the United Kingdom knowing he couldn't leave the country due to his various legal issues.

Assuming Rock is actually planning on working at Extreme Rules, that could mean WWE is going to throw us a curve and he could retain the WWE championship at WrestleMania 29 in his rematch with John Cena only to lose the belt a month later. It's also possible he loses it but gets his automatic rematch and they pile up on the money in the third and final showdown between the two.

What throws this into question is the fact that Rock is currently scheduled to begin filming "Hercules" after WrestleMania, so if he does any dates with WWE, he's going to be stretched very thin.

We'll just have to do what we always do and stay tuned.
