In a word, no.
Despite rumors running rampant all weekend that Brock Lesnar was in Miami, Florida, to talk to World Wrestling Entertainment (WWE) to iron out some details on a reported one-year contract, he did not, in fact, crash the party at the WrestleMania 28 event that took place at Sun Life Stadium last night (April 1, 2012).
This despite the fact that he was backstage.
That doesn't mean he won't be making an appearance on WWE television soon. In fact, Monday Night Raw takes place tonight at the American Airlines Arena in Miami and speculation is high that the company will announce the main event to next year's WrestleMania 29 at the show.
And those plans could very well include Lesnar.
In the meantime, it looks like that shameless promotion from UFC President Dana White on Twitter may have helped push a few pay-per-view buys but it didn't lead to Lesnar showing up in WWE.
