Frolov was skating around after an ACL tear.
If it's something like that, we'd be lucky to see Fox in the playoffs. Would effectively be a season ender for this team.
Svechnikov took a few shifts after tearing his last year.
6-7 months is best case scenario for ACL recover after surgery so yeah, thats basically the year for him unless we get to the cup finals and play deep into that series.
I do think that @duhmetreE is more likely correct that they're trying to nip things before they become lingering.
How likely is an ACL? They're not nearly as common in hockey as football right?
Yeah football ACL tears mostly happen via non contact. That happens in hockey too but its way less common because you aren't planing your foot into turf and trying to burst off of it. Svechnikov is the only guy I can think of who recently had an ACL tear with out anyone within 5 feet of him.
ACL tears happen in hockey and I wouldn't call them rare. I don't know that the force was there for it on this play but the inward bowing of the knee when Aho ran into him is where I'm a bit concerned along with the further evaluation comment but that was applied to Chytil as well. There are certain things that could have been done immediately to rule out an ACL tear but we wouldn't hear about that.
