Sabres' Dahlin (upper-body injury) out Tuesday vs. Canadiens

BUFFALO, N.Y. -- Sabres captain Rasmus Dahlin is day-to-day with an upper-body injury. The blueliner left Monday's 5-3 win over Florida in the second period and did not return. Dahlin was quarterbacking Buffalo's power play when he blocked a shot from the slot off a faceoff and immediately went down to a knee. The defender recovered enough to skate off to the bench in discomfort before heading to the team's dressing room. Sabres coach Lindy Ruff confirmed Dahlin was hurt on the play and would not travel with Buffalo to Montreal for the second half of its back-to-back on Tuesday.
