National Hockey League referee Trevor Hanson's black-and-white pinstriped uniform may have had some extra colouring on it Thursday thanks to a scary incident during the Coyotes-Sabres game. 

Hanson took a puck to the face off a deflected shot from Phoenix defenceman Oliver Ekman-Larsson in a bloody scene during the second period of Buffalo's 3-2 win. The puck changed directions after hitting the crossbar and struck Hanson in the nose.

He'd leave the game with a towel pressed up against his face to get some medical attention, but would later return in the third period to finish the game.
