Fourth liner Chris Wagner was missing, injured blocking a shot during the Boston Bruins’ Game 3 victory. On top of Wagner, goaltender Tuukka Rask, captain Zdeno Chara and defenseman Steven Kampfer were all not on the ice.
You’d have to assume, at least in the case of team captain Chara that a maintenance day was the reasoning. Given the giant defenseman is in his forties, it’d be quite fair to limit the amount he practices, especially ahead of a potential series-clinching Game 4.
Tuukka Rask was made to work incredibly hard, especially in the first period against the Carolina Hurricanes in Game 3.
