If the rumors floating around both last night (March 31, 2012) and today in Miami, Florida, are to be believed, former Ultimate Fighting Championship (UFC) Heavyweight Champion Brock Lesnar will make his return to WWE at tonight's WrestleMania 28 pay-per-view extravaganza at Sun Life Stadium.
Again, all reports up to this point are unconfirmed. Lesnar was sighted in Miami with a heavy duty security detail who guarded him closely and attempted to keep his presence from being known.
He's been in talks with WWE for some time now to make a return to the world of professional wrestling. Even before he retired from mixed martial arts (MMA) following a knockout loss to Alistair Overeem at UFC 141 on Dec. 30, 2011, in Las Vegas, Lesnar was promoting and appearing in the WWE '12 video game.
Now, according to various reports from the Wrestling Observer, Brock has signed a one-year deal with WWE and will make his debut soon. Whether or not that's going to be tonight is up in the air.
If you're wondering what UFC President Dana White thinks about all this, he commented on the rumors on his Twitter account a short while ago:
"Good luck to my man @TheRock tonight!!! I will be watching the @WWE plus all the rumors of (to)nights event sound like it's gonna be crazy! :)"
Lesnar's history with professional wrestling dates all the way back to 2000 when he signed with WWE not long after leaving college, where he was a national champion amateur wrestler.
He quickly rose to fame when he was called up from the developmental territory to the main roster and became one of the biggest stars in the business. But his intense travel schedule and frequent injuries, not to mention a grueling life on the road, led him to leave WWE in 2004.
He would go on to fail out of the NFL and wrestle in Japan before bursting onto the MMA scene in 2007. He infamously made his UFC debut in Feb. 2008, losing via kneebar to Frank Mir in the first round.
But he impressed in his debut and it wasn't long before he was fighting for -- and winning -- the heavyweight championship.
Unfortunately, his fighting career was severely hampered by not one but two bouts with diverticulitis, an intestinal disorder that nearly took his life and ultimately helped lead to his decision to retire just this past year.
But instead of just hanging around Minnesota and hunting up in Canada, Lesnar is headed back to the industry that first made him a household name, bringing his career full circle.
