The Sabres' struggling defense could be without its most consistent player tonight.

Christian Ehrhoff took only a few twirls around the rink in Scotiabank Place this morning before retreating to the dressing room. Coach Lindy Ruff confirmed on his WGR radio show this morning that Ehrhoff has a muscle strain that kept him out of practice Monday.

Andrej Sekera, who got hurt Saturday in Montreal, made the trip but only rode a bike this morning and did not go on the ice with the rest of the team.
