Shane McMahon announced that the WWE Title match at Fastlane will now be a Fatal Four-Way match. The winner of Baron Corbin vs. Dolph Ziggler on next week’s SmackDown Live episode will be included in the match.

What’s interesting about this change is that the Nationwide Arena was advertising the match last month as having five participants but neither Ziggler or Corbin were advertised. Don’t be surprised if another name is added to the mix.
