As the official skated to center ice and turned on his microphone to announce the call, McAvoy made his way to the penalty box and swore at the referee just at the right time:
Don't think Charlie McAvoy agreed with the call from hockey
Unfortunately for McAvoy, the mic was on, the entire arena heard McAvoy's curse words. The referee though didn't skip a beat and simply replied, "no!"
The league has stict policies about questioning their officials, but I'm pretty sure McAvoy will avoid any funny for this interaction.
