Oh I see. Well he was far away from Skucas but his stretched arm was not. It did make a slight contact, it may be hard to see but on slow motion you can def see the contact, the problem is that such contact in most cases is just too light to be called a foul, specially on such decisive moment but I think the fact that Skucas slipped right after it (he slipped on his own though) was what bought refs in.
