Cooley (lower body) was placed on injured reserve by the Flames on Friday, Pat Steinberg of QR Calgary 770 AM reports.
Cooley was pulled from Wednesday's loss to the Oilers after one period due to his lower-body injury, and he's considered week-to-week after landing on injured reserve. Dustin Wolf will start Friday's home game against Seattle and figures to operate as the Flames' primary netminder in Cooley's absence, while Arsenii Sergeev was recalled from AHL Calgary on Friday.
