At the very end of the second period the New Rangers thought they had taken a 2-1 lead on a goal from Ruslan Fedotenko as the NBC clocked showed 0.1 seconds left on the clock. The play was initially called a goal on the ice, but upon further review in the Toronto war room the play was ruled no goal as the official NHL time read 0.0 before the puck completely crossed the line.
Here is the video which shows the overhead replay with the official NHL time on the screen and shows the call was right. Why NBC did not have the official NHL time burned into the telecast today is a different question.
