Report: Sting having ongoing issues after knee surgery

TNA World Champion Sting was described as being in a lot of pain before and after the Genesis PPV last night in Charlotte, NC. Sting recently underwent knee surgery and is having a hard time getting around reports The injury angle with Rhino on the show was designed by TNA to keep the match short and simple for Sting. His ongoing knee issues caused many to speculate that Sting will retire when his latest contract with TNA expires late this year.
