Sabres' Daniel Catenacci: Undergoes concussion testing

Catenacci had to go through concussion protocols Thursday after getting a hit to the head, reports John Vogl of The Buffalo News.

Catenacci was on the receiving end of a brutal hit by Flyers defenseman Radko Gudas, who caught him with his head down. Catenacci got tangled up at center ice in a puck race with Pierre-Edouard Bellemare and clearly didn't see the hit coming. He skated off the ice on his power, however clumsily, and did not play in the remaining 3:33 of the game. There has been no official word on Catenacci's status, so consider him day-to-day for now.
