Jere Lehtinen and Brendan Morrow suffered injuries in Saturday's game against the Red Wings.
After the game, Stars coach Marc Crawford said both players were day to day.
"We have to hope they're fast healers," Crawford said.
Morrow, a member of Canada's Olympic team, went to the locker room late in the first period after blocking a shot. He played one shift in the second period before being ruled out for the third period.
Lehtinen played only 3 minutes, 15 seconds of the opening period. The team later announced that Lehtinen is day to day with an undisclosed injury.
Lehtinen, a member of Finland's Olympic team, has already missed 16 games with hip and groin injuries.
