I'd need to see the replay on the Chytil before making a call on it just yet.
You'll notice if you haven't, Sillinger follows CBJ's normal route for their controlled breakout. Forwards always swing there as I've noticed post hit.
But couldn't tell if Sillinger stuck out the elbow when making contact. Chyil also moved to retreat last minute.
That said, Sillinger could have easily adjusted his route slightly to avoid coming to close to Chytil, and guys will normally do that. Suspicious he chose to not slightly change route to be further above Chytil
