WWE 'SmackDown' Spoilers 8/13/15: SummerSlam Build Continues

WWE taped the August 13, 2015 edition of Thursday Night SmackDown from Portland, Oregon, and the show continued to build to SummerSlam in 10 days, so let's get to the spoilers.

WWE World Heavyweight Champion Seth Rollins opens the show with a promo and dares United States Champion John Cena to accept his challenge for the title vs. title match at SummerSlam despite the fact that WWE has already announced the match.
