Both the Toronto Maple Leafs and Boston Bruins can punch their tickets to the postseason on Tuesday night.

The Maple Leafs (39-24-15) can clinch a playoff spot by defeating the Washington Capitals in regulation or overtime and having the Tampa Bay Lightning lose to the Bruins in any fashion. Or, if the Maple Leafs win in any fashion (shootout included) and the Lightning fall in regulation, the Maple Leafs will reach the postseason for the first time since 2013.

The Bruins (43-30-6) can clinch their playoff spot with a regulation win over the Lightning on Tuesday night at home. That would ensure the Bruins would have 94 points, which would then be the maximum total the Lightning could accrue this season and the Bruins would own the tiebreaker with 42 regulation or overtime wins to Tampa Bay's maximum of 38. The Bruins missed the playoffs in each of the previous two seasons.

The Ottawa Senators (41-27-10), who are tied with the Bruins at 92 points (and own a game in hand), do not have a clinching scenario Tuesday when they host the Detroit Red Wings. The Senators have lost five straight games and have been jumped by the Maple Leafs for second in the Atlantic Division.

The Montreal Canadiens clinched the Atlantic Division on Monday night, while the Capitals, Pittsburgh Penguins, Columbus Blue Jackets and New York Rangers have already clinched their playoff spots.

All eight playoff spots have already been clinched in the Western Conference.
