Doughty led the NHL with an average of 26:50 of ice time in the regular season, and had 60 points (10 goals, 50 assists) in 82 games. He played 28:02 in Game 1 and had six shot attempts and six blocked shots.
"[Muzzin] has been the No. 2 defenseman on our team for a long time and is a big part of the team," Doughty said. "We have a different look when he's on the ice, so definitely happy to have him back. As for me, I'm just eager to get out there and make a difference in the game."
The Kings also reunited the lines of Alex Iaffalo, Anze Kopitar and Dustin Brown, and Tanner Pearson, Jeff Carter and Tyler Toffoli, at the morning skate. Los Angeles has scored one goal in 155:23 in the series, none at even strength.
"We need more offense; we know that," Stevens said. "We need more zone time; we know that. I think just in general our whole game has just got to take a step here."
Perron, who missed the past eight games with an upper-body injury, skated on the left wing with center Cody Eakin and right wing Ryan Carpenter at the morning skate.
Golden Knights coach Gerard Gallant said he still had to speak to the trainers.
"There's a chance he might play," Gallant said.
