Hungary captain Dominik Szoboszlai has criticised the response from medical staff after Barnabas Varga suffered a head injury during their win over Scotland.
In a tense clash that both teams needed to win to keep their hopes of qualification to the knockout stage alive, Varga collided with Scotland goalkeeper Angus Gunn in the 67th minute.
The game was paused for around seven minutes as the 29-year-old forward lay motionless on the ground.
Both teams motioned for medical staff to rush on, and Varga was initially treated on the pitch as players and stewards held up sheets.
