Adrian Kempe had a goal and an assist for the Kings (22-14-9), who are 2-7-5 in their past 14 games. Cam Talbot made 32 saves.
“That’s unacceptable,” Los Angeles coach Todd McLellan said. “We’re up 3-1. We’re maybe not playing our best, but the stupidity that went into that loss is unexplainable. I could come up here and tell you that, ‘Hey, in the past we’ve been close, maybe we didn’t get some luck around the net.’ But I haven’t, until now, been able to come in and say, ‘Boy, we played really dumb.’ And that’s what we did.”
After falling behind 3-1 in the first period, Buffalo responded with goals 2:08 apart in the second period.
Peterka cut it to 3-2 at 8:22 on a breakaway set up by Quinn’s pass while on his stomach at his own blue line, and Quinn tied it 3-3 at 10:30 on a wrist shot from the high slot.
Alex Tuch gave the Sabres their first lead of the game at 5:49 of the third period, one-timing Eric Robinson’s feed in the right circle to make it 4-3.
“I think when you have those games and you see that you can come back, it gives you energy for the rest of the season,” Peterka said.
