David Wagner has apologised for his over-zealous celebration
Huddersfield stunned Leeds with a late goal to win the derby clash 2-1 and leapfrog their local rivals in the Championship table.
Michael Hefele's 89th-minute winner prompted David Wagner to sprint down the touchline to join in the celebrations with his players.
But this led to a huge bust-up on the sidelines between the two teams, resulting in both Wagner and Garry Monk being sent to the stands.

And while the Huddersfield boss has apologised for his actions which sparked the ugly scenes, he has claimed he is unsure if he can be "friends" with Monk.
"It is all part of the emotion of the game but maybe this should happen with the players on the grass," Wagner said.
"For me, celebrating with my players is not disrespectful but perhaps it is in British football culture. This culture is different in Germany.

"I celebrated with my players and jogged back to my technical area and Garry tried to nudge me.
"Then I went to speak to him. But this was not possible at this time. I had to go to the stands."
Asked if he could "still be friends" with Monk, Wagner added: "I don't know him well enough to know that."
