The Flames were without one veteran during Tuesday's practice at the Scotiabank Saddledome.
Mikael Backlund, who left Saturday's game with a lower-body injury in the pre-season win over the Oilers, did not practice with the team but skated on his own this morning.
Calgary general manager Brad Treliving deemed his absence as precautionary and expects him to be back with the group for Wednesday's practice and ready for Thursday's season-opener in Denver.
Without Backlund's participation, here are how the lines shook out on Tuesday morning:
Johnny Gaudreau - Sean Monahan - Elias Lindholm
Matthew Tkachuk - Sam Bennett - Michael Frolik
Milan Lucic - Derek Ryan - Andrew Mangiapane
Tobias Rieder - Mark Jankowski - Austin Czarnik
Mark Giordano - TJ Brodie
Noah Hanifin - Travis Hamonic
Oliver Kylington - Rasmus Andersson
Elias Lindholm - Sean Monahan - Johnny Gaudreau
Milan Lucic - Sam Bennett - Austin Czarnik
TJ Brodie - Rasmus Andersson
