Lehtonen was the first to go down, leaving just 5 minutes, 31 seconds into the game with a groin injury. Lehtonen was injured while stopping a shot by Coyotes defenseman Derek Morris on a play that was offsides. He was attended to by the Stars trainer and then was helped off the ice.
"It's a little bit of a groin pull there," said Stars coach Glen Gulutzan. "We'll see how it is. It's one of those things you don't see the extent until you see it the next day."
Gulutzan said Lehtonen is unlikely for Monday's game at Colorado.
Daley, who left the game in the first period as well with what Gulutzan said appeared to be a back issue, is also unlikely to play Monday.
"Dales we're not quite sure," Gulutzan said. "I think it was a little bit of his back, tweaked his back. We're not sure the extent of that."
Fiddler left the game late in the second period with a groin injury and is listed as day to day.
Morrow is expected to return Thursday against Ottawa. Goligoski and Burish may not be back for two to three weeks.
