Sheahan (upper body) did not travel with the team to Long Island for Sunday's matchup with the Islanders, the Detroit News reports.

Analysis:

Neither Sheahan nor Erik Cole (upper body) made the trip, but the team has not commented on how long it expects to be without both players. Sheahan is reportedly showing improvement, however, so it does not appear he'll be sidelined for too much longer.
