Buffalo went back in front with 31.3 seconds left in the period on a fluky goal right off a faceoff, as the puck caromed off defenseman Cam Fowler and got behind Gibson. On a night when not much went right for Anaheim, it was fitting that ended up the game-winner.
"That's the way it's going," Gibson said. "If we're not scoring, we have to be better defensively. I have to be better. When it's not going good, that's the way the bounces are. You saw that on the second goal. A shot that's not going really going toward the net. That's the way it is."
The Ducks had some chances to tie it fall by the wayside, most noticeably when Logan Shaw had the puck bounce to his stick with a yawning net in front of him, but he pushed it wide.
Anaheim sent Gibson to the bench for an extra attacker with just under two minutes left, but only managed to dodge a couple of empty-net chances by Buffalo before Johan Larsson eventually scored from near the red line to put the game away.
"These games right now seem to be played in parts," Ducks coach Randy Carlyle said. "We haven't been able to put together 60 minutes. You can tell we're starting to squeeze the sticks. Loose pucks up for grabs, instead of calmly making a play or corralling the puck, we're slapping it away and throwing it away from ourselves. Usually that's a sign of confidence. That's the one thing we have to try and correct."
Anaheim, in the midst of having six of the season's first seven games at home, next plays Friday night vs. Montreal at Honda Center.
