If WWE could finally put together a deal that will entice him to sign, Sting could possibly make his debut in the company by being the person to induct the Ultimate Warrior into the hall of fame during Wrestlemania 30 weekend. The two were tag team partners at the beginning of their careers.
While he has yet to sign a contract with the company, there are already rumors that Sting could be utilized by WWE as the general manager of Monday Night Raw in the story lines. The belief right now is that it is highly unlikely that he will be working a match at Wrestlemania 30.
While the word is that the two sides are still negotiating, Sting is unlikely to work a match at Wrestlemania 30, even if he does come to an agreement with the company. The long rumored match with the Undertaker will not be taking place this year.
