Vince McMahon has always taken a hands-on approach to his shows. He's long had a tendency to change plot points at the last minute, or change match results hours or even minutes before they air.
 
According to multiple sources, including Dave Meltzer, Sean Ross Sapp, and Ryan Satin, McMahon was not impressed with Tuesday's planned Smackdown show, and ended up rewriting the whole thing, only hours before it was scheduled to air. It's further evidence that even though Paul Heyman has taken over Raw, Smackdown is still very much under McMahon's thumb. Eric Bischoff, who Vince assigned to lead WWE Creative on Smackdown, has apparently not started his tenure yet.
