Seguin missed practice on Monday and will be assessed again on Tuesday. Ruff said Seguin could be a game-time decision against the Minnesota Wild (8:30 p.m. ET; FS-SW, FS-N, FS-WI, NHL.TV)
Seguin leads the Stars and is tied for eighth in the League in scoring with 45 points. He is one of three Stars players to appear in all 48 games this season along with Radek Faksa and Devin Shore.
Dallas will be without Faksa against Minnesota after the center sustained a lower-body injury in a 4-3 overtime loss to the Washington Capitals on Saturday. Ruff said Faksa will miss at least two games.
"It doesn't look like it's serious, that's the good news," Ruff said. "And we have [the all-star break], so we might have got away with one there."
Faksa has 22 points this season and has been one of the Stars best faceoff men. Ruff wanted to use Faksa for the opening faceoff of overtime against Washington, but he was unavailable because of the injury. Jason Spezza lost the draw to Jay Beagle, who scored the game-winning goal 19 seconds into overtime.
Stars captain Jamie Benn also missed practice Monday after breaking his nose against Washington. Ruff said Benn will play, and missing practice was precautionary.
Jiri Hudler and Lauri Korpikoski, who each were healthy scratches against Washington, could play.
