Unusual incident at Pride Park. The first time the ball went out of play at the start of the second half Darren Bond went over to talk to his fourth official Ollie Langford as Derby had brought on a substitute at half time without informing the officials. The player, Nathan Byrne, was duly summoned and cautioned. Byrne was making his debut for Derby having joined from Wigan a few days earlier so received a yellow card in the first minute of his debut for the club.
I have seen a comment on line saying the yellow card was incorrect in law but I am not certain if that is correct.
The yellow card was incorrect:
Law 3.5
If a substitution is made during the half-time interval or before extra time, the procedure must be completed before the match restarts. If the referee is not informed, the named substitute may continue to play, no disciplinary action is taken and the matter is reported to the appropriate authorities.
Oh dear, very bad for a professional referee to be getting that wrong!
