"It looks like Tyler will be back for us," Ruff said.
The news wasn't as good for forward Ales Hemsky, who sustained a groin injury playing for Team Czech Republic at the World Cup. He has yet to skate in a full practice.
"It doesn't look like Hemsky will be able to play [opening night]," Ruff said. "He's had treatment, I would look to see him get on the ice tomorrow again. Not for practice, but we'll wait and see."
In addition to Hemsky, the Stars are missing forwards Cody Eakin and Mattias Janmark because of knee injuries. Eakin could be out six weeks, while Janmark will miss at least five months, and could be out the entire regular season.
To add a veteran presence, the Stars signed left wing Lauri Korpikoski to a one-year, $1 million contract Monday. He had been released from a professional tryout with the Calgary Flames on Sunday.
"A good veteran forward that plays a two-way game," Ruff said of Korpikoski. "With the amount of injuries we had and our depth being depleted, it's a good addition."
Korpikoski, 30, had 10 goals and 22 points in 71 games with the Edmonton Oilers last season.
He said the Stars' injury problems made them a possibility when his time with the Flames ended.
"I decided to jump on it," Korpikoski said. "Calgary was nice enough to let me explore other things.
"I've played against these guys a lot, chasing them around on the ice. They're a high [energy] offense, play with fast pace. They have good players. They've had some success and they want to win."
During practice Monday, Korpikoski took shifts on the fourth line with Adam Cracknell, Devin Shore, and Brett Ritchie.
