Reigns is looking for payback after it was revealed that Rowan was the person who pushed stage equipment on him several weeks ago on SmackDown Live.
Daniel Bryan has continued to deny any involvement in the incident but it's clear that this storyline is leading to an eventual Bryan vs. Reigns match on a future pay-per-view. The original plan was to do Bryan vs. Reigns at SummerSlam but the feeling was that it was too early for that match to occur so it was delayed.
The match announced for Clash gets Reigns on the pay-per-view without burning through the big match with Bryan right away.
