The speculation linking Sting with a return at SummerSlam has been intense. The old saying "no smoke without fire" could apply, maybe he will be turning up this Sunday. Initially, the belief was that he would feature in the Wyatt match. It was thought that he'd be teaming with Roman Reigns, with his appearance being one of the reasons to buy the show. That hasn't transpired, but he could still end up involved in that match. Having him come in as a surprise would send the message that WWE events are so much more than just what's advertised ahead of time. He's expected to be in a match at Night Of Champions, so maybe he'll return at SummerSlam and set it up.
