Another possible cause of the backstage heat between CM Punk and WWE is the fact that he did not want to do the job to Triple H at Wrestlemania 30. Punk felt that the company was going in that direction since he has refused to sign a contract extension with them.
Colt Cabana, a good friend of CM Punk in real life, was given another tryout not too long ago with WWE, but the company opted not to sign him to a contract just yet. It now appears that he is being considered for a possible role on the upcoming WWE Network.
There is a very good chance that we only have five more months of seeing CM Punk, as his contract with WWE expires in July of this year. The former heavyweight champion has openly talked about leaving the company on his own terms, so it will take some convincing from management to get him to sign a new deal.
