I'm still not 100% on this. That angle makes it look like it, but it also looks like the jersey flares out at contact so it may even have been the contact itself that moves his elbow (or maybe even just the jersey itself as it returns to the previous position almost immediately after) and it creates an illusion that he extended the elbow.
Also McDavid doesn't really change his path whatsoever and the elbow stay in the middle of the chest areas whereas Johanneson completely changes direction before contact and his stances has his head at a really low level. I just can't look at this and think there was any intent at all to catch him in the head.
Either way, hopefully he has a quick recovery as he is indeed hurt and will miss time from the incident.
