Opposing managers David Wagner and Garry Monk were both sent to the stands after being involved in an ugly face-to-face confrontation in Sunday's West Yorkshire derby.
With rivals Huddersfield Town and Leeds United locked together at 1-1 and entering the final minute of the game at the John Smith's Stadium, up popped defender Michael Hefele to put the home side back in front.
The Huddersfield boss reacted to that dramatic last-gasp goal by then sprinting the entire length of the touchline to celebrate with his own players, leading to a scuffle with his Leeds counterpart on his way back to the dugout.
Meanwhile, both sets of players were also involved in an on-pitch fracas, with the visitors adamant Hefele's winner should have been ruled out for offside as the likes of Pontus Jansson, Liam Bridcutt and Elias Kachunga were all booked.
