Busted Open Radio reports that Sting has officially signed his WWE Performers contract. The contract would consist of 6 appearances for the company. The first one, obviously, was at the Survivor Series so he has 5 appearances left on the current contract.
He will be likely wrestling at WrestleMania 31 so that means he has 4 dates left on WWE TV. I would guess that they’ll likely save those dates for February and March when they are hyping up his match with Triple H or whoever he ends up facing.
If all goes well there’s always a chance that they could have Sting another deal after WrestleMania.
