Huddersfield Town are one of the Championship's cleanest sides this season, statistics suggest.
The Trinity Mirror Data Unit have crunched the numbers and found that the Terriers have been pulled up for a foul an average of just once every 4.8 minutes that their opponents have been in possession of the ball.
In Championship games this season, Town's opponents have averaged 55 per cent possession, or 49 minutes a game.
Town have been pulled up for a foul on their opponents 195 times, 10.3 per game.
That means that the Terriers foul an opposition player an average of once every 4.8 minutes that they are in possession of the ball - the joint third longest foul-free period of any side in the Championship along with Cardiff.
Birmingham have the longest foul-free period, five minutes, followed by Charlton (4.9 minutes per foul), then Town and Cardiff (4.8), and Rotherham (4.7).
At the other end of the scale, Millwall come out as the most frequent foulers in the league.
With 272 fouls awarded against them (14.3 per game and the highest in the league) and an average of 45 minutes without the ball, Millwall are pulled up for a foul once every 3.1 minutes that their opponents are in possession.
That's followed by Reading (3.3 minutes), then Bolton and Derby (both 3.4 minutes).
