The Montreal Canadiens and Boston Bruins are bitter rivals on the ice, but away from it, they’re coming together for a good cause.

The Canadiens held a pregame ceremony honoring Denna Laing prior to Tuesday’s matchup, and the video tribute served a dual purpose to promote the jersey auction being held.

Before the video, Bell Centre public address announcer Michael Lacroix made the following announcement in both French and English:

“Fans, tonight your Canadiens are working together with the NHL and Boston Bruins to support a member of our Hockey Family — Denna Laing.

As a member of the NWHL Boston Pride, and one of the pioneers in a breakthrough moment for her sport, Denna Laing participated in the Outdoor Women’s Classic. Tragically, Denna suffered a severe injury playing the sport she loves.

You can join your Canadiens, the NHL and the Bruins in supporting Denna by bidding on game worn jerseys from tonight’s game. One hundred percent of the proceeds from the auction will go to the Denna Laing Fund. Visit AUCTIONS.NHL.COM/DENNALAING or DENNALAINGFUND.ORG.”
