Sabres defenseman Christian Ehrhoff will be out for an extended period after he was injured in Friday night's 3-1 loss to the Capitals. Ehrhoff left the game after a fight with Washington's Troy Brouwer late in the first period and did not return. Buffalo coach Lindy Ruff said Ehrhoff was going to "miss some time ... probably weeks." Ruff did not disclose Ehrhoff's injury.
