CM Punk responded to a fan on Twitter, who told him his “knee sucks:”

Later that day, Punk posted this on his official Twitter account:

 

As of writing, there isn’t any reports of CM Punk suffering any new injuries, but it should be noted that CM Punk wasn’t cleared for in ring action until the Raw 20th Anniversary show, back on January 14th.  That same night he wrestled Ryback in a brutal Tables, Ladders and Chairs match.

This may be Punk voicing his displeasure with WWE, or he may be continuing his feud with The Rock.  Maybe showing how he continues to wrestle everyday while Rock wrestles only on pay-per-views.
