The Sky Bet Championship is widely thought of as one of the most competitive footballing leagues in the world - if not the most - and a lot of the reason as to why is down to the physicality and passion shown within it.
One weekend you will have the table toppers beaten by relegation zone strugglers and the next you will see an absolute thrashing with similar oppositions. The sheer unpredictability of the division makes it very exciting to keep tabs on.
Sometimes, though, the nature of the Championship can bring about plenty of disciplinary actions, with referees in the English second tier often dishing out yellow and red cards throughout matches.
Ranked by the most ‘points’ collected - one for a yellow, three for a red via a second yellow, and five for a straight red - here are the dirtiest teams in the Championship this campaign, sourcing data from Transfermarkt.
