OTTAWA -- Senators captain Daniel Alfredsson has a groin injury and isn't expected to play Saturday against Philadelphia.
Ottawa's top scorer was injured during Thursday's shootout loss to Pittsburgh. He had three assists in the game but wasn't able to take a shootout attempt.
Senators coach John Paddock says his captain is day-to-day, but "I don't think that day-to-day includes playing tomorrow."
Ottawa has dropped two straight games for the first time this season.
Alfredsson leads the Senators with 16 goals and 30 points.
