"I want to do obviously what's best for the team," Seguin said. "I'd say it was a good day."
Seguin was second on the Stars with 73 points and tied for second with 33 goals in 72 games.
Rookie forward Mattias Janmark, who missed the final three games of the regular season because of an upper-body injury, also practiced without a red jersey Wednesday.
"They [Janmark and Seguin] are both doing well," Stars coach Lindy Ruff said. "They're both available to play. It'll just be a decision is if they're ready now."
Janmark, who had 15 goals and 29 points in 73 games, split shifts at left wing on the fourth line with Travis Moen. Vernon Fiddler centered that line with Colton Sceviour on the right side.
Defenseman Alex Goligoski missed practice Tuesday because of an illness but was on the ice without restriction Wednesday. He was second on Dallas in average ice time per game at 23:50.
"Just a little flu big. In and out, so it's good. I feel good today," he said.
Goligoski returned to his customary spot in Dallas' top pair alongside normal partner John Klingberg, who was fifth among NHL defensemen with 58 points this season.
