Rhett Warrener was sent for a MRI yesterday to check out his knee.
Warrener, who was listed as suffering a charley horse after leaving Tuesday's game, was sent for further tests after doctors examined him yesterday, according to assistant coach Jim Playfair.
"He didn't seem to think it was that bad and that's the most important indicator for us right now and what we go on," Playfair said.
Results from the test are expected today.
Warrener limped out of the Saddledome yesterday without speaking to reporters.
The defenceman suffered his injury early in the Nashville game. He stepped up to hit Greg Johnson in the open ice and went down.
Johnson lifted his leg to protect himself and it drove into Warrener's thigh, Playfair said.
"That was the main complaint from Rhett when he came off the ice, that his thigh was sore," Playfair stated. "When the doctors got looking at him, they wanted to check his knee out to make sure there was no damage done to his knee."
Should Warrener not be able to play tonight against Dallas, Cale Hulse will draw back into the lineup.
Roman Hamrlik, out since late January after needing surgery on his hand from being hit by a puck, practised with the Flames yesterday but won't play.
"We'll see the next three or four days, with some harder practices where he is but Rhett's injury doesn't speed up Roman's recovery," Playfair said. "We want to make sure he's 100 percent when he comes back."
Hamrlik wasn't scheduled to return until mid-March when the procedure was done.
"It has to get a little bit stronger but it's my second day with the team and I finally was able to start shooting," Hamrlik said. "It's not bad but still not there where it's supposed to be."
Right winger Darren McCarty missed Tuesday's game due to the flu but skated yesterday and said he plans to face the Stars.
