One thing that amazed me the other night was that Drysdale made Coventry players leave the field after receiving treatment from a physio in tackles that Notts players received a booking for, one was Biamou when him and Duffy clashed heads and I don't remember the second, possibly when Allessandra fouled someone?
They changed that rule and announced the change a while back either before this season or last - If a player is fouled and hurt by an opponent who subsequently receives a yellow or red card for the challenge, the injured player may be quickly treated on the pitch without the need to leave the field of play.
We did see it happen once this season and most fans weren't aware of the change and went mad but I can't understand why Darren Drysdale wouldn't be aware of it or enforce it, it means that Coventry were down to 10 men twice as a result of being fouled.
