Drew Doughty has been suspended one game by the NHL Department of Player Safety.
The Los Angeles Kings defenseman was disciplined for an illegal check to the head of Vegas Golden Knights forward William Carrier in Game 1 of the Western Conference First Round of the Stanley Cup Playoffs on Wednesday.

Doughty would not be eligible for Game 2 of the best-of-7 series on Friday (10 p.m. ET; NBCSN, CBC, TVAS, ATTSN-RM, PRIME). Los Angeles lost Game 1, 1-0.
"We are preparing accordingly and will move forward," Kings general manager Rob Blake said.
The incident occurred at 9:58 of the third period. There was no penalty assessed on the play. Carrier did not return to the game.

Doughty played 28:02 in Game 1. He led the NHL in time on ice per game during the regular season (26:50) and was seventh among defensemen with 60 points (10 goals, 50 assists), his NHL career high. He is considered a contender for the Norris Trophy, given to the player voted as the NHL's best defenseman.
"I think he's the best [defenseman] in the League, and he's so easy to play with," said Kings defenseman Oscar Fantenberg, who made his NHL playoff debut paired with Doughty in Game 1. "I don't think that's good for the team, but I think somebody else has to step up and take those minutes."

Injured defenseman Jake Muzzin (upper body) has been practicing with the Kings but hasn't been cleared for contact, and coach John Stevens did not have an update on him Thursday. Muzzin, who averaged 21:39 per game this season, has not played since March 26. Defenseman Kevin Gravel is likely to make his NHL playoff debut in Game 2.
Carrier is day to day with an upper-body injury, Vegas coach Gerard Gallant said Thursday.
