Leeds United have defended their treatment of defender Robin Koch who stayed on the field after a sickening clash of heads in the Whites' defeat to Manchester United.
The club issued a statement on Monday, insisting concussion protocols were followed after the collision with United's Scott McTominay early in the match at Elland Road.
However, Koch sat down 15 minutes after receiving treatment, which involved heavy strapping to his head after he received a deep cut above his eye, and he was substituted at that point.
The incident, in Leeds' 4-2 loss to Manchester United, has provoked a sharp reaction for the Professional Footballers' Association, which claimed the event demonstrated that concussion rules in elite football are failing players.
