no penalty if you ice it. just keep icing it.
very interesting that most of the refs don't know the rule. don't call it
They know the rule, they just waive it off as it hit some mystery stick on the way down because they want to get the game over. Between crazy parents screaming at them, psycho coaches on the bench, entitled brats on the ice, and the rink management trying to keep to a schedule, it's hard to blame them.
