After falling behind 3-2 after two periods, the Montreal Canadiens answered the Bruins' physicality in the third period by scoring two unanswered goals to snap Boston's six-game win streak and defeat the B's 4-3 on Sunday night at the TD Garden.

Max Pacioretty's wrister from the point tied the game at 3-3, five-and-a-half minutes into the third, and then David Desharnais made it 4-3 midway through the period by crashing the net and knocking home a loose puck out front, which ended up being the game-winner.

The Bruins held a spirited 3-2 lead after two periods. Patrice Bergeron and Dougie Hamilton scored the only two goals of the second period after falling behind 2-1 through the first 20 minutes.

After Bergeron and Hamilton gave Boston the lead, Milan Lucic and Brandon Prust dropped the gloves in the first fight of the night. Moments later, Zdeno Chara went out of his way to give Canadiens defenseman Alexei Emelin a beatdown, after Emelin hit Tyler Seguin with a low cross check at center ice in the final minutes of the second period.

Seguin went down in pain and angrily went right back to the dressing room. As that was happening, Chara purposely skated to the other side of the ice and went after Emelin, dropping the gloves and hitting him with punch after punch.

Chara was given an instigator penalty, a fighting major, and a 10-minute misconduct. Seguin returned to the game shortly after.

The first period didn't see as much fighting, but it did see three goals in a span of 1:06. Montreal scored two of those goals, midway through the first period. Tomas Plekanec put home a power-play goal to give the Canadiens a 1-0 lead, then 50 scones later, Seguin finished a nice feed through the slot from Bergeron to tie the game at 1-1.
