I doubt Kylington will be in game shape when he gets back so it’d likely be him sitting, especially if Tanev is out with injury

Otherwise I believe it would be Stone coming out of the lineup in favour of Weegar who’d be moved to RD. Zadorov has played very well this season as has Stone, but Stone is the weakest defensively

Need to Trade Kylington for a Forward or maybe Hanifin who was really disappointing with Andersson in the playoffs and so far this season

No one knows when he’s playing, no one’s asking questions cause he’s asked for space. If he comes back tomorrow he’s missed a whole training camp and a month of the season, they may get him into a game before Christmas, unlikely at this rate.
He’s on a deal that walks him directly to UFA with no bought UFA years which certainly hinders his value in a trade, the market for him is a little tough cause no rebuilding teams will move a piece the Flames want and no competitive teams are going to pony enough draft capital to make it worth it for Calgary.
He’s had one good season, he’s not worth nearly as much as fans on here think, if he was he wouldn’t be a piece in every armchair GM post. at this rate best case scenario is he comes back and plays well for Calgary but who knows when that is.
