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.
The Rock called in a favor from a famous friend to help out with his new show, Wake Up Call, which will be airing on TNT soon. Dana White, who is the president of UFC, made a guest appearance on one of the early episodes. Rock post a picture of the two of them together on the set via Twitter.
In a move that might have been encouraged by Dana White to promote the potential return, Alistair Overeem called out Brock Lesnar after defeating Frank Mir at a UFC event this past weekend. Lesnar is attempting to work with WWE on making his MMA return possible.
