It appears that the confusion has arisen following our man's red card sustained against Nottingham Forest earlier this season. Pratley was sent off following two bookings - but in a strange quirk of refereeing law, it has been recorded as one yellow card and one red card, from which Pratley has already served a ban.
Keeping up? No? Tough, because it gets more complicated:
So basically, the yellow card doesn't technically count. Even though Pratley has actually received five yellow cards, in terms of the FA's records, he has only received four.
Therefore, if he gets a booking between now and the end of 2013, he will get a one-match ban.
