The widely held belief is that Brock Lesnar would be immediately booked into a rematch against Alistair Overeem if he decides to return to UFC. Overeem was the person that defeated him for the heavyweight championship before he decided to retire from MMA and return to WWE.
According to reports, Bellator is interested in signing CM Punk, if he wanted to try changing careers. It has been a well known fact that Punk is a big fan of MMA, where he is frequently seen at UFC events. As many already know, he recently walked out on WWE after some disagreements.
Aside from ruining an on screen segment with Chris Jericho, another issue between Roddy Piper and WWE was the fact that the company wanted to restrict his ability to make appearances on other shows, which Piper refused to agree to since it might hurt his son's MMA career.
While rumors of his MMA return have died down a little since making his on screen return to WWE, it appears that Brock Lesnar is still in discussions with Dana White about making a return to UFC. Apparently, he's trying to do both industries at the same time.
It is being said that one of the things that is preventing Brock Lesnar from making a return to UFC is his deal with WWE. The belief is that Vince McMahon has Lesnar on an exclusive deal, where he would not be able to compete in mixed martial arts during that tenure.
With rumors swirling about a potential return to UFC, former world champion Brock Lesnar has become a topic of discussion within WWE, as management is still hoping for him to work a big money match against the Undertaker at Wrestlemania 30.
