After a tragic day in Ottawa, the NHL and the Pittsburgh Penguins proved that they are about more than just hockey. The Penguins decided to play the Canadian national anthem prior to their game against the Philadelphia Flyers Wednesday night.

The lyrics to "O Canada" were placed on the scoreboard to encourage fan participation in the singing of both anthems. It was a touching moment that emphasized that sometimes there's more than just the game.

Fans and Canadians showed their appreciation to the Penguins on Twitter.

Great show of support by the game in Pittsburgh. You're next, Edmonton. Can't wait to hear this! <a href="https://twitter.com/hashtag/OttawaProud?src=hash">#OttawaProud</a> —@surkhriarh
