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.
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.
