The Red Wings will be without star forwards Pavel Datsyuk and Henrik Zetterberg on Tuesday when they visit the Philadelphia Flyers. But Jimmy Howard could be available — and Joakim Andersson, also. That’s where the injury list stands heading into the Flyers game, which will be important in terms of the wild-card chase. Zetterberg was a late scratch for Sunday’s game against the Florida Panthers, and general manager Ken Holland confirmed to The News that Zetterberg will not make the trip to Philadelphia. Zetterberg has a reoccurence of back problems — he missed 11 games in December with issues — but the severity of this problem, and whether it’s related to the previous problems, remains to be seen. Zetterberg took two big hits in Friday’s victory over Montreal which could have triggered new issues. Datsyuk last played in the Winter Classic on Jan. 1 and has been out since with a lower-body injury. Datsyuk is hopeful of returning later this week. He’d like to play in games before the Sochi Winter Olympics. Holland also said Datsyuk did not make the trip to Philadelphia.
