Sam Lafferty and Jack Quinn scored, JJ Peterka had two assists, and Ukko-Pekka Luukkonen made 24 saves for the Sabres (16-22-5), who had won two straight.
“I thought the second period, [it was] embarrassing the way we played,” Buffalo coach Lindy Ruff said.
“We had [offensive] zone time, didn’t get to the inside, didn’t get pucks to the net, passed the puck around the perimeter, looked for the pretty play, and eventually it caught up to us. And to give up a goal in the last couple minutes on the play, unacceptable. Just embarrassing, actually.”
Lafferty gave Buffalo a 1-0 lead at 2:37 of the first period when his wrist shot from the right wall deflected off the stick of Seattle defenseman Vince Dunn and over Daccord’s left arm.
Quinn made it 2-0 on the power play at 17:17. His one-timer from the left face-off circle went in off Daccord’s blocker.
Ryker Evans cut it to 2-1 at 12:48 of the second period when his wrist shot from the right circle deflected off the leg of Sabres forward Jason Zucker and over Luukkonen’s left pad.
“I think it gave us hope and life,” Bylsma said of the goal. “I think we were playing much better at the start of the second period and continued and [had] maybe a little bit of a feeling that … to see one get by [Luukkonen] and get that goal just kind of continued the hope.”
Andre Burakovsky tied it 2-2 at 19:12. Luukkonen stopped Mahura’s point shot, but Burakovsky was at the right post to shovel in the rebound on his backhand.
“We’ve seen it too many times this year where we give up one and it’s just a disaster,” Sabres center Dylan Cozens said. “And then they get another and then another. I don’t know why it keeps happening, but we’ve got to figure it out and find a way to not let that happen.”
Oliver Bjorkstrand put Seattle ahead 3-2 at 3:08 of the third period when his shot from in front bounced up and went in off the glove of Buffalo defenseman Jacob Bryson.
