BOSTON -- Anthony Beauvillier scored 21 seconds into overtime, and the Boston Bruins lost in their first game in seven days, 4-3 to the New York Islanders at TD Garden on Thursday.
Beauvillier scored on a rebound in the crease after Nick Leddy's shot trickled under the arm of goalie Jaroslav Halak. It was Beauvillier's second overtime goal in as many games.
"Well first of all, it's a privilege to be out there in overtime, to have the chance to make your team win," said Beauvillier, who scored the winner in a 2-1 victory at the Philadelphia Flyers on Monday. "It shows the trust that the coaching staff has in you, and I take a lot of pride in that, and I just want to do my job out there. I got fortunate over there with the loose puck, but I thought we did a really good job tonight just staying with the process and coming from behind."
The Bruins (16-8-5) were playing for the first time since March 18 after having two games postponed because of NHL COVID-19 protocol. Tuukka Rask made six saves in the first period but didn't return after the intermission because of an upper-body injury. He was replaced by Halak, who made 17 saves.
There was no update on Rask's status after the game.
"[We] didn't defend well enough in front of our net," Boston coach Bruce Cassidy said. "Had to switch goalies, sure it wasn't easy on 'Jaro' to go in a situation like that, and they finished around the front of the net. We could've been harder, could've used an extra stop. Got a point out of it. We were in a position to get two. Again, they played winning hockey in the third period better than we did."
Jean-Gabriel Pageau had a goal and two assists, and Semyon Varlamov made 29 saves for the Islanders (22-8-4), who have won three in a row and are 5-0-0 against the Bruins this season.

Karson Kuhlman scored his first of the season to give Boston a 1-0 lead at 11:42 of the first period, shooting through a screen from along the left boards.
Steven Kampfer also scored his first of the season to extend the lead to 2-0 at 17:35 with a one-timer on the power play.
Pageau cut it to 2-1 at 7:21 of the second period, nine seconds after the Islanders killed a double-minor against Scott Mayfield.
"I knew we were going to end up with a point tonight once we got that goal," New York coach Barry Trotz said. "If they had got that third goal, I don't think we'd be sitting here tonight with any points. But I liked our resiliency and stayed in the fight."

Josh Bailey tied it 2-2 at 4:33 of the third period on a wrist shot from the right circle.
Oliver Wahlstrom gave New York a 3-2 lead at 17:04, but Anders Bjork scored 54 seconds later on a one-timer from the slot to tie it 3-3.
"I think we talked about it before the third, they're a good third-period team," Kampfer said. "We had some lapses there and it cost us the game. That's on us in the room to make sure that we come out … we've got to be ready for everything that they throw at us. We were a couple bounces too short."
NOTES: Pageau's goal was his 100th in 468 NHL games. … Wahlstrom has scored six points (four goals, two assists) during a five-game point streak. … The Bruins played in front fans for the first time this season at TD Garden, which is allowed to operate at a 12 percent capacity, according to Massachusetts regulations. Attendance was 2,191. … Kuhlman was injured blocking a shot in the third period and did not return. There was no update on his status. … Boston forwards David Krejci, David Pastrnak and Craig Smith were removed from NHL COVID-19 protocol Wednesday.
