WWE's backup plan for Roman Reigns at Night of Champions

Dean Ambrose replacing Roman Reigns at Night of Champions?

According to Bryan Alvarez of F4WOnline.com, WWE actually had 2 Night of Champions scripts in place prior to Roman Reigns’ hernia surgery, one of which did NOT have Reigns wrestling at the PPV. While no official replacement has been announced for Reigns in his match against Seth Rollins at the PPV tonight, WWE might have been toying with the idea of not having the match take place(just like Dean Ambrose vs. Seth Rollins at Battleground PPV), and something else could go down at the PPV, including possible Dean Ambrose involvement.
