Craig Anderson wears No. 41 for the Ottawa Senators, but Saturday night called for a heartfelt and temporary change.
As the club explained, it's the favorite number of his wife, Nicholle, who was recently diagnosed with cancer.
A member of the opposition acknowledged the tribute.
The Senators and five other NHL teams are holding their Hockey Fights Cancer night on Saturday.
Anderson and his teammates are wearing decals in honor of Nicholle during the game.
