EDGE Analysis

Look for more updates to come in the next day or so as Chara undergoes testing ahead of Thursday's Game 5 in Boston. The defenseman suffered the injury with just over three minutes left in the second period; though he returned to the team's bench in the third with a reinforced shield, he did not take the ice the entire third period after being advised by team doctors.
