Following his loss to John Cena at WWE Battleground, Kevin Owens has been moved from the main event scene down to the upper mid-card. According to sources, Owens’s position is now comparable in WWE to the likes as Dolph Ziggler, Cesaro and Rusev, as opposed to the main eventers like John Cena, Randy Orton or Seth Rollins. The idea of having Owens work a main event feud right off the bat with Cena was to “get him known” to the casual WWE fanbase.
Many in the company expected Owens to win the US Title from Cena at the Battleground pay-per-view, but obviously that didn’t happen. He’s been taken out of his feud with Cena so Cena can move on to Seth Rollins. As of now, there are no plans to have him featured at SummerSlam; he’s currently set to face Finn Balor at NXT Takeover: Brooklyn the night before the pay-per-view.
Of course, plans can and always do change on an hourly basis but as of now, he’s not booked for SummerSlam at all.
