Radek Faksa remained unfit to play Monday, Stars coach Rick Bowness said, and Roope Hintz will be a game-time decision.
As part of the NHL Return to Play Plan, a team is not permitted to disclose player injury or illness information.
The Stars can advance to the Stanley Cup Final with a win in Game 5 of the best-of-7 series in Edmonton, the hub city for the conference finals and Cup Final.
Faksa did not play in Game 4 on Saturday, a 2-1 Dallas win, after he was injured in the third period of Game 3 on Thursday, which the Stars won 3-2 in overtime.
Andrew Cogliano replaced Faksa in the lineup for Game 4 and had an assist on Joe Pavelski's tying goal at 11:34 of the second period. Jason Dickinson moved from left wing to center, taking Faksa's spot on the fourth line.
Hintz was injured in the first period of Game 4 when he appeared to collide with Stars forward Corey Perry. He left the game at 12:42 of the first.
"We have no update on Roope," Bowness said. "It's too early. We'll meet with our medical staff tomorrow."
If Hintz is unable to play in Game 5, forwards Justin Dowling, Ty Dellandrea,
Nick Caamano
and
Jason Robertson
are available to replace him. Each has been a healthy scratch for all 20 of Dallas' postseason games.
"We'll get together later when we know who's ready to go as a staff and we'll discuss that, who is going in," Bowness said. "We'll figure that out when we know exactly what we're working with."
Goalie Ben Bishop remains unfit to play, Bowness said, but he is practicing. Bishop has not dressed for the past six games; Jake Oettinger has been the backup to Anton Khudobin.
Bowness said defenseman Taylor Fedun was cleared to play Saturday and took warmups prior to Game 4 but did not dress for the fifth straight game.
Joel Hanley
has played in Fedun's absence.
Vegas coach Peter DeBoer said he didn't want to give injury updates Sunday when asked specifically about forwards Mark Stone and Tomas Nosek. There were no updates Monday because of technical difficulities with DeBoer's media availabilty,
Stone appeared to sustain an injury in the second period of Game 4 when he blocked a shot from Pavelski with his foot. He left the game but returned for the third period, although it appeared as if he was laboring.
Nosek was unfit to play in Game 4 after he was injured in Game 3. Nick Cousins replaced him and played 14:06.
Since the conference format was adopted for the 1981-82 season, teams with a 3-1 lead in the conference finals are 34-1 (97.1 percent). The New Jersey Devils rallied to defeat the Philadelphia Flyers in the 2000 Eastern Conference Final and then won the Stanley Cup.
