Jamie Benn scored the winner in a shootout in the Dallas Stars' 4-3 victory over the Ottawa Senators on Sunday.
The game had a number of twists and turns, but perhaps the most disconcerting for the Senators was the injury to goalie Craig Anderson.
With 1:32 gone in overtime, Anderson went down hard after being hit by Valeri Nichushkin. He was taken off the ice on a stretcher after he appeared to take a knee to the head.
Anderson faced 36 shots before Robin Lehner was forced into action.
Antoine Roussel, Ray Whitney and Nichushkin scored for the Stars (6-6-2). Kari Lehtonen stopped 36 shots.
Lehtonen stopped Milan Michalek, Jason Spezza and Bobby Ryan in the shootout.
Ryan, Erik Karlsson and Jason Spezza scored for the Senators (4-6-4), with Ryan tying it with 9.6 seconds remaining in regulation.
