The Boston�Bruins have lots of question marks heading into Game 5 against the St. Louis Blues.
Of course the main question mark surrounds the status of defenseman Zdeno�Chara and Matt�Grzelcyk.
While Chara was understandably nowhere to be found during Wednesday's practice, the good news was that Grzelcyk was on the ice however he was wearing a no-contact jersey.�
Urho Vaakanainen skated alongside Grzelcyk on the fourth defensive pairing which could indicate he'll be Cassidy's seventh defenseman if Chara can't go tomorrow.�
John�Moore skated in Chara's place on the first pairing.�
