Both players were injured during the Stars' 6-5 overtime loss to the Carolina Hurricanes on Thursday.
Crawford said Fistric was evaluated Friday morning, and the decision was made to keep him out of the next three games at least. Crawford said the protocol with concussions is that a player can't play until a certain number of days have passed without any symptoms, so they'll continue to monitor Fistric.
Daley, who has one goal and four assists in 33 games this season, was put on injured reserve, retroactive to Dec. 16, with a shoulder injury. He is eligible to return Dec. 26 in Colorado.
To take Daley's place on the roster, the Stars recalled defenseman Maxime Fortunus from the Texas Stars of the AHL. Fortunus, who has yet to make his NHL debut, has five goals and four assists this season with Texas.
"He's played very effectively down at the minor league level," Crawford said of Fortunus. "Their defense has been the best part of their game along with their goaltending. We're rewarding a guy that's been a leader in that department. ... He's very aware in the defensive zone, and we can use a smart guy back there to go along with the crew we've got."
Daley had five points in 33 games before his injury. He was second on the team in ice time at 22:25 and was an integral part of the power play and penalty kill units.
The Stars next face the Detroit Red Wings on Saturday.
