Kevin Owens made his WWE main roster debut in May 2015, essentially answering John Cena's US Title Open Challenge.

The main event isn't the only title match on the card. Last week, Tama Tonga and Talla Tonga captured the WWE tag team championships in a triple threat match. The MFTs, flanked by their legendary father Haku, grant former champions Damian Priest and R-Truth an immediate rematch.

Punk beat Zayn for the WWE Championship, much to the delight of the Chicago faithful, which set the stage for a title defense against Cody Rhodes this weekend at SummerSlam. Since Punk and Rhodes are both babyfaces, some have theorized that there could be a heel turn in order to spice things up.
