Brodie was immediately taken to hospital and later discharged. He's now recovering at home.
Flames doctor Ian Auld said Brodie's episode is likely related to fainting rather than a brain issue, but the veteran is still undergoing tests, according to TSN's Bob McKenzie.
"He's feeling good. He's feeling sore... All tests have come back normal," Treliving said.
Brodie was standing alone at practice when he collapsed. He was alert and responsive while being transported to the hospital.
The 29-year-old has spent his entire 10-year career with the Flames, and he's posted eights assists in 21 games this season. With Brodie out of the lineup, Calgary has recalled blue-liner Oliver Kylington from the AHL.
