"He went and saw some doctors yesterday. Nothing surgical, which is good," coach Peter DeBoer said Tuesday. "I would say day to day, but it's probably in between day to day and week to week. Good news for the most part."
Stone was injured during a 6-2 loss to the Los Angeles Kings on Oct. 14. The forward has three assists in two games this season after leading the Golden Knights in assists (40) and points (61) in 55 games last season. He scored eight points (five goals, three assists) in 19 Stanley Cup Playoff games.
Max Pacioretty also did not play in a 3-1 loss to the St. Louis Blues on Wednesday. The forward is week to week with a lower-body injury sustained blocking a shot against the Kings. He is tied for the Vegas lead with three points (two goals, one assist) in two games.
"There's a heightened awareness with those guys out of the lineup to make sure we've got that detail in our game maybe earlier in the season than you normally would," DeBoer said. "We're two games in, but we're going to need that in order to keep our head above water here."
Pacioretty was second on the Golden Knights last season with 51 points (24 goals, 27 assists) in 51 games, and scored 11 points (five goals, six assists) in 13 playoff games.
"With those two key guys out of our lineup, everyone knows that they have to step up," defenseman Zach Whitecloud said. "It's not just the defensemen. Obviously everyone knows who's out of the lineup. It's on us as a team to step up and fill what they do on a nightly basis."
Evgenii Dadonov and Nicolas Roy replaced Pacioretty and Stone on a line with center Chandler Stephenson against St. Louis. Roy had three shots on goal in 15:39 in his season debut, and Dadonov (17:20) and Stephenson (19:05) each had two shots.
"Some guys are going to have to step up and there's going to be opportunities there," Roy said.
