Mansfield Town boss Paul Cox insists the Stags are not a dirty side after a run of three red cards in three games.
Louis Briscoe, Tom Naylor and Anthony Howell have all been dismissed in recent weeks.
But Cox told BBC Radio Nottingham: "I don't think there's a problem. If there was, something would be done about it.
"What I've tried to get here is honest players who are competitive and want to win. But there's nothing malicious or dirty about any one of my squad."
