Bruins forward David Krejci fined $5K for slashing Islanders' Mathew Barzal

The incident occurred during New York's Game 4 win on Saturday. In the second period, Barzal delivered several uncalled cross-checks to Krejci's back. The Bruins center eventually responded by turning around and hitting Barzal between the legs with his stick. 

Krejci was initially given a five-minute major for spearing, but it was reduced to a two-minute minor for slashing upon further review. 

After the game, Barzal called the slash by Krejci "a little vicious," adding he was surprised the referees reduced the penalty. 

Krejci scored Boston's lone goal in a 4-1 loss to the Islanders on Saturday night, while Barzal had a goal and an assist. 

The Bruins and Islanders will meet again on Monday night at TD Garden with the series tied 2-2.
