The FA and the ÂProfessional Game Match Officials Limited â€“ which is the refereesâ€™ body â€“ have launched Âinvestigations to find out how Wednesday winger Helan was booked twice but not sent off.
But referee Mick Russell had wrongly noted down Helanâ€™s team-mate Michail Antonio for the first booking and failed to spot the error.
Helan admitted: â€śFrom a personal point of view, I was just happy to complete 90 minutes.
â€śI do not know what happened with the bookings. That is the refereeâ€™s decision and you would have to ask him.â€ť
