Tottenham boss Ange Postecoglou says he won't condemn Yves Bissouma after his dismissal in victory at Luton.
The midfielder received a second yellow card for diving.
Postecoglou said: "The referee said he had simulated and Biss made a mistake. He has been brilliant for us this year. He made a mistake and the good thing is how he reacts to these things.
"His team-mates made sure that mistake didn't cost us and I'm sure when Biss gets back in the team he will reciprocate and make sure that whatever else happens he can get us over the line.
"These things happen in football. It's disappointing. With all these things I always look at reactions. What are we doing about it? I thought the reaction was outstanding."
