The New York Islanders were stunned by the Ottawa Senators on Thursday night, as they fell 3-2 on a last-second goal at Canadian Tire Centre. Brady Tkachuk broke a 2-2 tie with 13 seconds to play, as the Senators captain deposited a Jordan Spence rebound past Ilya Sorokin to send the Islanders to a regulation loss to a team chasing them in the standings.
