Evan Bouchard scored the lone goal for the Oilers (39-29-9), who ended a season-high five-game winning streak and finished a four-game homestand 3-1-0. Connor Ingram made 28 saves.
“When things are going well, you forget about those details, those first couple strides coming back, get a little extra aggressive on the pinch,” Edmonton coach Kris Knoblauch said. “You’re thinking maybe you’re overconfident, getting a little bit lazy or whatever it is, I think we’re just not paying attention to those details.
“So, a lot of stuff that we’ve just got to clean up. Easily fixable.”
Howden put the Golden Knights up 1-0 at 11:43 of the first period. Eichel's initial wrist shot from the right face-off circle rebounded off the blocker into the left circle, where he snapped the puck past a diving Ingram.
Sissons made it 2-0 at 5:44 of the second period, redirecting a backdoor feed from Mitch Marner as he drove to the net.
Lauzon extended the lead to 3-0 at 8:04 with his first goal in over two years. Eichel slid a pass to Lauzon in the left circle, where he beat Ingram with a snap shot short side for his first goal in 113 games dating back to Feb. 22, 2024, when he was a member of the Nashville Predators.
“It was a great moment I was waiting for it for a long time,” Lauzon said. “I thought our team played unbelievable tonight and it’s a huge win for our club.
“I thought we were relentless on the forecheck, we were good down low and we put a lot of pressure on those 'D.' And it paid off.”
