This definitely warrants some attention.

One of the biggest names in professional wrestling in the past 10 years has suddenly found himself unemployed.

Following a first round technical knockout (TKO) to Alistair Overeem at tonight's (Dec. 30) UFC 141, former WWE Superstar Brock Lesnar retired from the sport of mixed martial arts (MMA).

"My hats off to Alistair Overeem. I've had a really difficult couple of years with my disease. Tonight is the last time you will see me in the Octagon. I want to thank everybody -- the Fertittas, Dana White. Everybody you've been great. I'm here to say that Brock Lesnar has officially retired. I promised my wife, my kids. If I won this fight I'd fight one more time for the title. If I lost, I'd retire."

It's been a rough couple of years for "The Next Big Thing" who was perhaps hours away from death when diverticulitis and the Canadian healthcare system formed a tag team and doubled up on the former NCAA champ's intestines. He made a return at UFC 116 and won a rousing fight against Shane Carwin but came up short a few months later against Cain Velasquez.

Booked opposite Junior Dos Santos during a season of the UFC reality show The Ultimate Fighter, Lesnar was set to meet the Brazilian to decide the number one contender to the heavyweight crown but his gut trouble resurfaced. Now with a second consecutive loss, the big guy has called it quits.

Right now, it isn't a question IF Lesnar returns to the WWE but WHEN. There should be no doubt that Vince McMahon personally gave his former Superstar a post-fight phone call to A, console Lesnar on his loss and B, ask if the Minnesota native wants to make a truckload ... no, a boatload ... no, there isn't a vessel that's been built yet that could hold the amount to money the two men could make.

Following Lesnar's announcement, WrestleMania became a worldwide trend on Twitter.

What do you think, Cagesiders? Will we see Lesnar in Miami?
