Former TNA World Champion & WCW World Champion Sting is said to be very close to signing a WWE deal as company officials have been told that Sting will wrestle one match minimum for the company and then announce his retirement, leading to an internal belief that Sting vs. The Undertaker will be a lock for the WrestleMania 31 pay-per-view in California and that Sting will possibly be inducted into the 2015 WWE Hall of Fame.
