Goal "That Wasn't" -- How Did That Happen?

Folks, if you were watching the Notre Dame vs. North Dakota NCAA Hockey Tournament game tonight -- you saw what looked like the game winning goal with 0.5 seconds left on the clock.

The photo above shows the game clock with time left when goal was scored!

The TV clock showed that -- as did the "green light" (video below) that went off showing the goal was scored in regulation time...

Well, the referees called it a NO GOAL -- forcing OT, which Notre Dame fortunately prevailed.

But, what if they had not?

It will be interesting to see if the NCAA releases a statement later tonight or tomorrow on why they disallowed the goal...
