National Hockey League roundup

Letang, widely considered a candidate for the Norris Trophy, left the game against the Arizona Coyotes at 15:15 of the second period. After Letang released a long outlet pass deep in his end, Coyotes right winger Shane Doan hit him and Letang fell backward into the end boards.

Letang needed assistance as he left the ice and was taken to a hospital for evaluation and was released Sunday. It's unclear how long he will be sidelined.

Letang has a history of concussions and suffered a stroke last year. He is third on the Penguins with 54 points (11 goals, 43 assists).
