The Stanley Cup is on the line Wednesday night when the Boston Bruins host the St. Louis Blues for Game 7 of the Stanley Cup Finals.� The first update we got regarding Game 7 is that the NHL has chosen it's officiating crew which Bruins' fans can deem acceptable.� Later on Tuesday morning the Bruins hit the ice for practice.� For the first time in awhile, Bruins forward Chris Wagner joined his teammates.� It's a good sign and means that Bruins might be able to dress him for Game 7.� The Wellesley, Massachusetts, native might have a good chance to play because Matt Grzelcyk was on the ice but in a non-contact jersey.� More to come from Cassidy after practice.�
