The Oilers have been continuously involved in trade rumors all season thanks to their terrible goaltending performances so far this season. However, the team may have taken too long to make a move as they now may not be the only Alberta based NHL team to be in the market for a goaltender.
Another option for the Flames would be to make a trade. They could potentially play spoiler to their rival Oilers as their Northern neighbors have reportedly been heavily involved in the goalie market all season. Wolf will likely get the call up regardless as the Flames play tomorrow night and it is very unlikely that they could get a trade in order before then even if that is what the team decides to do.
It seems like the injury might be rather serious given the way Flames personnel, including Markstrom himself, reacted to the play. A such, a major move may not be as unlikely as some may believe. Upsetting the Oilers plans would simply be an added bonus.
