#1 The match doesn't technically begin, thus affecting the result
In this case, anything that could go wrong in a match may go wrong, and the match result could be one that fans wouldn't anticipate. In this instance, the match doesn't end up coming to be.
Ziggler could be so tired of all the extravagance that tends to follow Nakamura and be pushed to a point where he actually interrupts his entrance and beats him down mercilessly before the bell even rings.
We could see Nakamura make a comeback, and the two continue to battle back and forth. However, the bell would never actually ring, and officials would spend their time trying to separate them. A debut where there is no official match recorded would certainly disappoint the crowd watching both at home and in attendance.
