HITC Sport understands a number of Derby players were involved in a dressing room row after their draw with Rotherham.
Several Derby County players were involved in a dressing room row after their late collapse in the 3-3 draw with relegation threatened Rotherham United at the weekend, HITC Sport understands from sources close to the club.
Derby threw away a three-goal lead at the New York Stadium as Rotherham staged an unlikely comeback with three goals in the final seven minutes.
The Rams looked to be heading for all three points in their bid for promotion to the Premier League thanks to Chris Martin's strike and two goals from Tom Ince until their dramatic late collapse allowed Rotherham to steal a point from the game.
Sources have told HITC Sport that there were heated discussions among the players in the Derby dressing room after the final whistle as frustrations boiled over.
A source told HITC Sport: "I believe there was a few arguments in the Derby dressing room after the game as the players held an inquest into how they did not win the game.
"There was a lot of shouting going on and you can understand that emotions are going to be running high after such a game in such a crucial stage of the season."
Derby are currently in fifth place in the Championship table, six points off the automatic promotion places, but also just three points clear of the chasing pack in the race for the play-offs.
It remains to be seen if Derby decide to take any action in the wake of the row, but they will be looking to bounce back from the draw against Rotherham when they play host to bitter rivals Nottingham Forest next weekend.
