Defensive miscues continue to haunt the Boston Bruins.

Bruins goalie Jonas Gustavsson turned the puck over in the defensive zone during the first period of Friday's game against the Islanders. New York quickly capitalized when Johnny Boychuk found Casey Cizikas open in front of the net for the goal.
