The Vegas Golden Knights are preparing for a must-win Game 5 with the possibility that their captain, Mark Stone, won't be with them, according to Sin Bin Vegas.

The 33-year-old suffered an upper-body injury in Game 3 and was immediately announced day-to-day. He was a full participant in practice before Game 4 and played 21:42 of ice time. The injury has seemingly gotten worse and will force him to be out for a must-win Game 5.

With Stone out, Cole Schwindt will likely check into the lineup as he did not stay after practice with the expected healthy scratches. If he does play, it'll be Schwindt's playoff debut.

Brandon Saad has been nursing a lower-body injury, which has kept him out of the lineup since Game 2.

Fortunately for the Golden Knights, Kaedan Korczak and Ben Hutton remained on the ice after practice, indicating that although Alex Pietrangelo and Brayden McNabb did not skate, they should be in line to play.
