The cardiac kids do it again . What a way to end this amazing series between two upstart hockey teams .

Rasmus Dahlin scored 6:27 into the third period to tie the game at 2-2, and the Buffalo Sabres overcame a two-goal deficit to force overtime against the Montreal Canadiens in Game 7 of their second-round playoff series on Monday night.

Jordan Greenway also scored for Buffalo and Ukko-Pekka Luukkonen stopped 20 shots through three periods.

Phillip Danault and Zachary Bolduc scored first-period goals for the Canadiens. Jakub Dobes made 32 saves, including foiling rookie Konsta Helenius set up alone in front with 8:03 remaining.

Owen Power set up Dahlin’s tying goal by driving toward the net before feeding a pass down low to Dahlin, who snapped a shot into the open side, with Dobes late getting across to his right.

The Canadiens entered 12-0 when leading by two or more goals in a playoff Game 7. And they’re seeking to win a second seventh game this postseason.
