The end of the first period in Monday’s Maple Leafs-Kings game brought us a big moment of confusion involving LA goaltender Jonathan Quick.

With three minutes to play, Quick took a blow to the head during a scramble in front of his net. He fell backwards into his crease, and grabbed at his mask, clearly shaken up. Play resumed for another 109 seconds before officials notified the Kings that the goaltender needed to leave the game after the independent concussion spotters called in a mandatory evaluation.

After some confusion and hesitance from Quick, he left the game and Darcy Kuemper entered for only 37 seconds before Quick returned.
