Stone was originally listed as a game-time decision on Monday but was ruled out ahead of Tuesday's game in Los Angeles. Mattias Janmark will likely move up into the top-6 with Stone out.

Lehner missed the final game before the Christmas break and was not on the ice for Monday's practice, clouding his availability for Tuesday's game. Look for Laurent Brossoit to start if Lehner is unavailable.

Stone missed part of the Golden Knights' most recent game (Dec.21) and was not on the ice for Monday's practice. Golden Knights' assistant coach Steve Spott called Stone a game-time decision for Tuesday's game in Los Angeles.

Howden is the third Golden Knights' skater to go into protocol recently, joining Alex Pietrangelo and Evgenii Dadonov. Both Pietrangelo and Dadonov could be back for New Year's Eve vs. the Ducks, while Howden is likely to miss the next four games.

With Hill going into protocol, Zach Sawchenko has been recalled from the AHL and will serve as James Reimer's backup on Tuesday.

The Golden Knights are one of two teams left before the Christmas break but adding Pietrangelo and Dadonov to the COVID-19 protocol list muddies the chances of this game happening. If it does happen, the Golden Knights will be without their top defenseman.
