Roy has two assists in four games, but hasn't played since Jan. 24, when he sustained the injury. He'll miss his second game Monday when the Stars visit the Columbus Blue Jackets.
Here are the lineups the Colorado Avalanche and Edmonton Oilers likely will use tonight when they meet at Rexall Place in Edmonton. The Avs lineup is in flux a bit, as the team will be without team captain Gabriel Landeskog.
Injured: Nikolai Khabibulin
The third pick of the 2011 NHL Draft, Huberdeau has a goal and two assists in four games. He had all his points on opening night and has been held off the score sheet since then. However, he's third on the team with 13 shots on goal and is averaging 15:49 of ice time per game.
Huberdeau had an outstanding preseason with the Panthers in September 2011, but the team sent him back to Saint John of the Quebec Major Junior Hockey League for another season of development. With another half-season of junior hockey plus a solid turn at the 2013 IIHF World Junior Championship, the Panthers are reaping the reward for that decision.
"With Jonathan, the difference between an 18-year-old and a 19-year-old is huge," Panthers coach Kevin Dineen told the Miami Herald. "You see a difference in maturity, and he had that extra year to develop as a person and a player. He wasn't part of that important first step of us making the playoffs, but he's going to be with us for a long, long time."
The Panthers had before their sixth game, Tuesday at the Tampa Bay Lightning, to make a decision. Prior to Huberdeau playing in his sixth game, the team again could have sent him back to his junior team, delaying the start of his contract. Once he plays his sixth game, his contract officially stars. He still can be sent back to his junior team after that, but it would waste the first season of his deal.
Two-time Stanley Cup champion Petr Sykora has signed with Swiss club Bern for the remainder of the 2012-13 season.
Sykora, 36, had 21 goals and 44 points in 82 games with the Devils last season, and five points in 18 Stanley Cup Playoff games.
A 1995 first-round pick of the Devils, Sykora has 323 goals and 721 points in 1,017 games with the Devils, Anaheim Ducks, New York Rangers, Edmonton Oilers, Pittsburgh Penguins and Minnesota Wild. He won Stanley Cups with the Devils in 2000 and Penguins in 2009.
Injured: Cam Atkinson
Zibanejad, the sixth pick of the 2011 NHL Draft, has four goals and seven assists in 23 AHL games this season.
Zibanejad had one assist in nine NHL games at the start of last season.
He will be available for the Senators' next game, Tuesday against the Washington Capitals.
Galchenyuk had his best game of the season Sunday with a pair of assists in the Canadiens' 4-3 overtime win against the New Jersey Devils.
In four games, Galchenyuk has a goal and two assists, and is tied for the team lead with a plus-2 rating.
The Canadiens had five games to decide if Galchenyuk would remain with the team or be returned to his junior team, the Sarnia Sting of the Ontario Hockey League. Once a junior-eligible player skates in his sixth game, it starts the clock on the first season of his three-year, entry-level deal.
Laughton had no points and 10 shots on goal in five games. He averaged 11:32 of ice time per game and won 44.2 percent of his faceoffs.
"It's a difficult one," Holmgren told the team's website of the decision. "He played very well, but at the end of the day it was something that we talked about and it was in the best interest of the Flyers and also Scott.
"He needs to play [and] he needs to play in all situations. He's going back to a good team and he will play a lot in all situations. He's a good young prospect and the little bit of time he had here with us was good for him and good for us."
The Flyers had to decide prior to Laughton playing in a sixth game, which would have started the first season of his entry-level contract.
Laughton, the 20th pick of the draft, was the youngest player to skate in a game this season.
