BOSTON — However you say tired in French, the Montreal Canadiens have to know that’s how to describe the Bruins tonight.

The Habs took advantage of a Boston team playing the second half of a back-to-back situation to post a pair of third-period goals and outshoot Boston, 15-9, in the last stanza of a 3-1 win over the Bruins at TD Garden tonight.

Boston not only played last night in Pittsburgh, but rallied from two goals down in the third to win and then landed back in the Bay State after midnight.

Here’s a quick glance at the box score:

•Tuukka Rask is now 0-4-1 on the season despite stopping 38 shots.

•The Montreal power play entered the game last in the NHL in success percentage and the Boston penalty kill was first. So, of course, the Habs scored twice in five opportunities, including the game-winning goal by Brian Gionta.

•Shawn Thornton was the hits leader (5) and the shots leader (5) on the evening for the Bruins.
