Sergeev was recalled from AHL Calgary on Friday.
Sergeev got his first taste of NHL action late last season, and he'll rejoin the Flames ahead of Friday's game against the Kraken. Dustin Wolf has already been named the starter against Seattle, but Sergeev's promotion suggests that Devin Cooley (lower body) may be unavailable as a backup. Across six appearances in the AHL to begin the regular season, Sergeev has gone 4-2-0 with a 2.86 GAA and .907 save percentage.
