Excellent, proper news. Thanks, MSE. Is it unprecedented that there are multiple major infractions overturned by the higher-ups? There have to be some pretty tense meetings among officials.
In terms of volume, I can't really verify. By comparison to the supposed offense, the rescinded decision(s) would be similar to the next day's correction in a newspaper: page 5 in a small paragraph.
One high-profile instance came a few years ago in Chicago in a ridiculous call that had Lindros ejected. Chris Chelios went to bat, in a sense, for Lindros who would have been suspended the following game (automatic, amount of times he was ejected that season).
The reaction of the national broadcast crew on NBCSN last night was also pitiful.
I am pretty sure an Edmonton player had one rescinded a few years ago, too.
