The Sky Bet Championship is one of the most physical and unpredictable football leagues on the planet, let alone just in the United Kingdom.
There are shock results every weekend and teams often emerge as surprise packages, making it rather tricky to forecast who will win battles for various positions.
Said fights apply to individual matches, too, as players often put their blood, sweat and tears into anything from simply winning back possession to making reckless, last-ditch challenges.
With this competitiveness comes a lot of break-ups in the play and, in turn, plenty of fouls. For this very reason, refereeing is particularly important in the Championship.
Countless cards are often brandished throughout matches, whether that be of the yellow or red variety, and some teams have accumulated quite the total.
But which sides in the English second-tier are statistically the worst culprits and can therefore be deemed to be the dirtiest, as per Transfermarkt?
With one point per yellow card, three for each second yellow and five for a red, flick through the pages to see how all 24 clubs compare.
