Krug's injury -- as sustained in Game 4 against the Lightning on Friday -- concerns his lower body and he'll be reevaluated Saturday morning, Bryan Burns of the Lightning's official site reports.

EDGE Analysis

Krug was helped off the ice by trainers and ended up in a wheelchair after he violently crashed feet first into the end boards during the third period. The Bruins can ill-afford to lose the playmaking defenseman, especially now that the team is down 3-1 in the series.
