CM Punk to opt out of Extreme Rules?

Reports suggested that CM Punk‘s injury may force him out of the Extreme Rules. This may provoke the creative team to bring in both The Rock and  Brock Lesnar for the major event. However, some incorrect speculations suggesting a Rock vs Brock main event match at the Extreme Rules are making headlines. As of now, the availability of both of them for the event is almost certain, but who their opponents will be, is still a question mark.

A number of questions about CM Punk’s actual injury, are being raised in the WWE circles. Some reports suggested that he is hurt more badly than what people are speculating. Some of them even denied any kind of injury happening to Punk. However, other reports tell that he has received some injuries, but they are more minor than major. Rumours relating it to creative frustration or burnout are also making rounds.
