Wrestling Observer founder Dave Meltzer reported Friday that Lesnar has been in talks with WWE for several weeks and when this year's headliner Dwyane "The Rock" Johnson worked around whether a question about Lesnar could be a future opponent, the rumor mill began to heat up.
The WWE's biggest event of the year is Sunday's Wrestlemania 28 and there is speculation that Lesnar might make an appearance to help generate buzz for an appearance at the 2013 event. There is no indication that Lesnar wants to return to wrestling full time as he wasn't a fan of the road schedule before his departure in 2006.
According to Meltzer, Lesnar is no longer obligated to the UFC:
Dana White confirmed that Lesnar is legally able to do WrestleMania. He had been under a UFC contract but had retired from the promotion. White was not aware if Lesnar was doing the show.
Lesnar (5-3) retired at December's UFC 141 following a first round TKO loss to Alistair Overeem. The 34-year-old dealt with diverticulitis for more than two years, throwing his career into a state of chaos. He lost the title to Cain Velasquez in October 2010, snapping a four fight winning streak.
