Breaking Update: WWE In Talks With Major Name To Appear At WrestleMania (UPDATED)

F4WOnline.com and PWInsider.com are reporting that Brock Lesnar is in negotiations with WWE to make a surprise appearance at Sunday's WrestleMania XXVIII pay-per-view event at Sun Life Stadium in Miami, Florida. Negotiations are ongoing, but a source within the company says that there is a 50-50 chance that Lesnar will appear on the show.

The source went on to state that WWE wants Lesnar to appear and is hoping that a deal can be finalized within the next 24 hours.

Ultimate Fighting Championship President Dana White confirmed to F4WOnline.com that Lesnar is legally able to appear at WrestleMania on Sunday since he is no longer under contract to the organization. White was not aware if Lesnar was appearing on the show.

Lesnar hasn't made an appearance for the company since leaving WWE in March 2004 to pursue a career in the National Football League, which was short-lived. Following a brief fling in New Japan Wrestling, he stepped away from the industry entirely in 2006 to pursue a career in mixed martial arts.

Lesnar captured the UFC Heavyweight Championship from Randy Couture on November 15, 2008, and defended the title twice before losing the strap two years later to Cain Velasquez at UFC 121. Lesnar was then announced as a "legend" in WWE '12 last fall, and even filmed a commercial for the video game. Months later, Lesnar announced his retirement from the UFC following a loss to Alistair Overeem at UFC 141 last December, which prompted speculation of a return to WWE.

A writer for the Associated Press recently hinted at a Brock Lesnar match for the Rock at next year's WrestleMania.

"I'm not saying a thing," said a grinning Johnson with his eyebrow raised after being asked about the possible encounter. "I didn't say anything."
