WWE advertised that Roman Reigns’ SummerSlam opponent would be revealed during SmackDown Live, but that didn’t wind up happening.
While he walked backstage a number of backstage objects and scaffolding fell on him. He seemed to be okay, as he walked off and brushed off any medical help, but the announcement wasn’t made. Whoever set up the attack will probably be revealed in future weeks.

What a strange ending to SmackDown.
