GIF: Robin Lehner demands an answer from the officials

The Ottawa Senators suffered a late, third-period collapse on Saturday, eventually losing 5-4 in overtime to the Montreal Canadiens.

The Senators weren't happy with the interference run on goaltender Robin Lehner on the tying goal, which came with 0.4 seconds remaining in the third period. 

Lehner also wasn't happy with the overtime winner - he thought he had the puck under his pads but the play was never blown dead.

He and his counterpart Jared Cowen wanted answers, but not before he broke his stick over his knee.
