The Stars will seek to extend their point streak to seven games when they welcome the Blackhawks to the American Airlines Center on Tuesday night.
Crawford was forced to leave in the first period of Sunday's home game against Florida because of a lower-body injury, but Antti Raanta proved capable enough to help Chicago (21-6-5) end a season-high three-game skid.
"I don't think it's too serious, but when it's a goalie, it's a little more serious than with other players, because of how important he is to our team," coach Joel Quenneville said.
Raanta got some help in the 6-2 victory from one of the Blackhawks' most complete offensive performances of the season. Patrick Sharp and Patrick Kane had three points apiece, and Chicago scored on three of its four power-play opportunities.
The Blackhawks might have to rely on Raanta for the near future with Nikolai Khabibulin still sidelined with a groin injury. They recalled Kent Simpson from their AHL affiliate in Rockford, Ill., to serve as a backup and also placed forward Bryan Bickell on injured reserve (lower body).
Dallas (14-9-5) is dealing with injuries of its own and Vernon Fiddler is the latest. The center is expected to miss at least one week after suffering an upper-body injury in a 5-1 victory over Philadelphia on Saturday.
"Every team deals with it," coach Lindy Ruff told the team's website. "Early on we didn't deal with a lot and now we've dealt with two pretty serious ones on the backend. It doesn't look like Fidds will be a long time, so it's something we've got to get through, other guys have to elevate their play and fill bigger holes."
Dallas managed its lineup well enough to end a six-game skid to Chicago with a 4-3 road victory last Tuesday. After his club blew a three-goal lead, Antoine Roussel put the Stars ahead for good by converting a penalty shot early in the third period.
Chicago has won five straight in Dallas and earned two of those victories in November. The Blackhawks could extend that streak if they can continue their recent success on the power play.
Chicago has seven goals in its last 19 opportunities (36.8 percent) with a man advantage and killed off all five penalties Sunday after allowing opponents to go 5 for 11 (45.5 percent) on the power play in the previous four games.
The Stars are 2 for 22 on the power play in their last seven games but are hoping Tyler Seguin can help by building on his third career hat trick. Seguin also had an assist in Saturday's win after being held without a point in five straight games.
Sharp, meanwhile, will try to spark the Blackhawks by adding to his recent success against Dallas. He has six goals and seven assists in his last seven matchups and a team-best six points (two goals, four assists) in this season's three meetings.
Dallas' point streak is its longest since an 11-game run Feb. 21-March 13, 2012.
