Huddersfield Town manager David Wagner has described Rajiv van La Parra's behaviour in the club's 1-0 defeat to Reading on Saturday as "unacceptable".
The 25-year-old, who joined the Terriers from Wolverhampton Wanderers over the summer, earned a second yellow card for dissent with just 25 minutes played at the Madejski, paving the way for Roy Beerens to score the game's solitary goal late in the first half.
"For the red card Rajiv must take 100% of the responsibility. What he did was unacceptable," Wagner told reporters afterwards. "Mistakes happen, this was a big one and he knows this."
Wagner insisted that he was happy with the attitude of the players left on the pitch, however, after they fought valiantly in an attempt to take something from the game.
"This was a defeat I can totally accept because my players tried everything," he added.
"At the end, we possibly deserved more than one point, because we created good opportunities with only 10 men. I am very proud about how the players reacted after the red card for Rajiv."
The result allowed Norwich City to usurp Wagner's men at the top of the Championship table.
