Ehrhoff missed Buffalo's game in Ottawa on Tuesday with a muscle strain. Adam Pardy was recalled from the Rochester Americans of the American Hockey League and made his Sabres debut against the Senators. Pardy played 18:25 and recorded an assist in the 4-3 loss.
Sabres coach Lindy Ruff said seven defensemen, including Ehrhoff, will take part in pregame warm-ups Thursday. A decision will be made after that. Ehrhoff is Buffalo's highest-scoring defenseman this season with five points and has averaged a team-high 23:54 of ice time per game.
"Early indications are [Ehrhoff] should be able to make it, but no guarantee yet," Ruff said.
