Reliable sources within World Wrestling Entertainment do not believe that Sting has signed with the organization. However, this doesn’t mean Sting won’t join WWE at some point, but it does not appear that he is currently signed according to these sources. This could also be an attempt to quash the rumors and surprise people when Sting does make his WWE debut.
Sting is still listed on the TNA Wrestling website roster page. However, he has not re-signed with the company. It is believed that he is still a free agent.
