Anthony Duclair scored two goals for the Panthers (52-15-6), who moved 10 points ahead of the Toronto Maple Leafs for first place in the Atlantic Division with nine regular-season games remaining. Sergei Bobrovsky made 22 saves.
The Maple Leafs lost 5-2 to the Buffalo Sabres on Tuesday.
"We want to finish first," Huberdeau said. "Every win is important. We want to keep playing well, keep playing better heading into the playoffs."
Derek Grant had a goal and an assist for the Ducks (29-33-13), who are 2-11-4 in their past 17 games and were eliminated from playoff contention Sunday.
Gibson has lost his past 13 starts (0-10-3).
''I did my best," Gibson said. "One lucky bounce, then they make a nice play. They're a good team. When you give them a chance they're going to bury them, and they did there.''
Duclair tied the game 2-2 at 10:09 of the third period with his 30th goal of the season, a one-timer from a sharp angle off a pass from Sam Reinhart.
