"He's not feeling very good right now," Boudreau said of Fowler. "Stoll hit him pretty good from behind. (The NHL) has to look at that. He might be OK, or he might be out for a while. ... He was sort of KO'd."
Captain Dustin Brown scored two power-play goals for the Kings, who struggled in their first trip to Honda Center as the defending champions. Stoll and Justin Williams also scored, but the Kings (2-3-2) never led.
"Generally we're a pretty good defensive team, but we gave up a lot of really good scoring chances," Brown said. "I don't think we go into any game thinking we're going to have a 7-4 outcome, one way or another. That's not how we play the game, but tonight we weren't playing hard enough in the key areas of the ice. I think we should use this game as a wakeup call. We should use this as motivation to be better."
Los Angeles won five of the six meetings last season in the Freeway Faceoff series, which features only four games in this lockout-shortened season. The first meeting was a beauty filled with big hits, chippy play, aggressive offense and power-play proficiency from both teams.
Quick yielded Bonino's two goals on the Ducks' first three shots before coach Darryl Sutter pulled his Conn Smythe Trophy-winning goalie 5:49 in for Bernier, who stopped 17 shots in his season debut.
"They were probably jacked up (for a) home game against the defending Stanley Cup champions and their interstate rival," Kings forward Dustin Penner said. "We're pretty disappointed. We have to prepare better as a team. What we did last year won't be enough this year, and we know that."
NOTES: Bonino is the 14th Anaheim player to record one of the Ducks' 39 hat tricks in franchise history. ... With two power-play goals, Brown caught and passed NHL scoring king Wayne Gretzky for seventh place in Kings history. Brown has 63 man-advantage goals in 602 games. Gretzky had 62 in 539 games with Los Angeles. ... The Kings hadn't scored a road power-play goal this season, going 0 for 18.
