1920–21 Ottawa Senators season

Cy Denneny led the club offensively, scoring 34 goals, which was the second-highest total in the NHL, and his 39 points ranked him 3rd in the entire league.

Frank Nighbor had another great season with 18 goals, and Buck Boucher provided the team toughness, leading the club with 43 penalty minutes.

The league ruled that the Senators were over the total salary limit for players and Cleghorn was ordered to report to Toronto.

Cleghorn eventually reported to Toronto, but returned to Ottawa in time to play in the playoffs.

Ottawa finished the second half of the season with a disappointing record of 6-8-0, earning 12 and ranking third in the NHL, eight points behind the first place Toronto St. Patricks.

The Sens added a second goal less than five minutes later, as Georges Boucher scored to make it 2-0 Ottawa after two periods.

In the third period, Ottawa's Eddie Gerard scored the opening goal of the game, giving the Senators 1-0 lead.

Then in the fifth game, Jack Darragh scored both of Ottawa's goals in the 2–1 victory to clinch the Cup.
