I may be confusing the two injuries.

Perhaps I'm remembering the fact that Thiago played and then being surprised that he had a significant injury.

I know that VVD definitely got up and walked off on his own because I recall people (not here) making a big deal about how tough he was to walk on a torn acl (which isn't a big deal).

As for the VAR I don't think the issue was that it was not reviewed for dangerous play. I don't recall that VAR necessarily announces its intent to review a matter. My issue is that it was 100% reviewed by VAR. Because it was offsides the clear and obvious foul (in the box) was made irrelevant. However, a human reviewed that play and somehow didn't come to the conclusion that he did a dangerous play.
