No one on the ice.Who accused him in the first place? Another player or another ref?
Also, if it did happen why would the league lie and say it didn't, knowing at any moment some clip from a fan might hit youtube showing it clear as day? Or that peeps online would dissect the various angles and feeds looking for it?
I get cynicism when it comes to the NHL, but I don't think they would pretend something like that never happened at all if it did. Just would be too dumb to even attempt.
