Not coincidentally, WWE will invade the Wells Fargo Center in Philadelphia with its Royal Rumble pay-per-view (PPV) tomorrow night. Rock posting this picture and making clear he'll be in the same city on the same day as a major event doesn't necessarily mean he'll be at the show.

Then again, PW Insider has reported that Rock was spotted at the WWE hotel earlier this evening.

It's entirely possible Rock is simply providing an assist to WWE with promotion of one of its biggest PPV events of the year. But it's also at least possible that one of the open slots in the Royal Rumble match will be filled by a "Brahma Bull."

Or perhaps he'll be there to set up a match at WrestleMania 31?

There are quite a few possibilities, and interest is going to be high no matter what. In that respect, his mission may have already been accomplished.

Or not ... yet.

Stay tuned.
