I’ve never seen players being let onto the field in such a ceremonial way Mikautadze and the Czecch player were after their tackle. Is that normal procedure?

They were off the pitch, the linesman (I think it was) then gestured to them to step onto the pitch. Looked weird. Why were they off the pitch?
