The Washington Capitals could be without center Nicklas Backstrom for Game 4 of their first-round series against the Boston Bruins after Backstrom cross-checked Bruins forward Rich Peverley in the face following the final buzzer of Boston's Game 3 victory Monday.

Backstrom received a match penalty and according to NHL rules any player receiving a match penalty will be automatically suspended from further competition until the commissioner has made a ruling.

Capitals coach Dale Hunter said he expects Backstrom's penalty to be reviewed and rescinded.

Backstrom scored the game-winning goal for Washington in double overtime in Game 2.

The Bruins lead the series 2-1. Game 4 goes Thursday in Washington.
