A promising start to the regular season for the Washington Capitals has been potentially hindered by the loss of defenseman Matt Niskanen.

Niskanen, who left Friday's game against Tampa Bay after taking a slash to the left hand, has been placed on long-term injured reserve with what's being labeled an upper-body injury.

The veteran defenseman is considered week-too-week and is expected to be out a minimum of 10 games and 24 days by being placed on LTIR, per Cap Friendly.

Madison Bowey has been recalled from the Hershey Bears to fill Niskanen's spot in the lineup.

Niskanen averaged 21:09 of ice time through the first five games of the season, recording one assist and four shots on goal.
