Note to the Colorado Avalanche as they take on the Bruins in their lone trip to Boston this season: It isn't over until it's over.

Third-period comebacks have been a hallmark for the Bruins as they take a 13-game points streak (9-0-4) into Saturday's tilt. Boston has scored 12 of its last 13 goals in the third period or later, including three to rally from a 3-0 deficit in an eventual overtime loss to the Chicago Blackhawks on Thursday.

That defeat snapped an eight-game winning streak for the Bruins. Meanwhile, the Avalanche have won five straight and possess an offense as dangerous through all three periods as any team in the league.
