The Flyers evened the score on Hartman’s goal at 15:20 of the first. Ivan Provorov threw the puck at the net and Hartman was able to push the rebound by Greiss.
Islanders defenseman Johnny Boychuk left early after being hit up high by Flyers forward Jakub Voracek. Boychuk was down on the ice for several minutes before he went to the team dressing room.
The Islanders honored their late Hall of Fame general manager Bill Torrey before the start of the game. Members of Torrey’s family were on hand for a ceremonial puck drop and a tribute video was played in his honor.
Torrey died on May 2, 2018, at his home in South Florida at the age of 83.
He developed the Islanders into a dynasty that won four consecutive Stanley Cups from 1980-83.
