Capitals' Matt Niskanen: Exits Wednesday's contest with injury

Niskanen (upper body) has been ruled out of the remainder of Wednesday's matchup with the Bruins, NHL.com's Tom Gulitti reports.

Analysis:

Niskanen sustained the injury when he was boarded by Boston's Patrice Bergeron behind the Capitals' net in the first period of Wednesday's contest. Niskanen was initially deemed probable to return to the game, but he was later ruled out for precautionary reasons. The 30-year-old blueliner will be reevaluated Thursday ahead of Washington's matchup with the Sabres on Friday.
