Coach Fabio Capello said the Manchester United striker’s 74th-minute dismissal for lashing out in retaliation had been “a silly mistake”.
It completed a disastrous 24 hours as Rooney's father, also Wayne and uncle Richie, had been arrested on Thursday in an investigation into spot betting involving a red card in a Scottish premier League match last year.
Angry England boss Capello said: "It's a red card. You can't defend that. I'm not happy, absolutely. I spoke with him. He made a silly mistake and he said: 'Yes, sorry.' More than that, I can't do.
"It was not a mistake (to play Rooney). He made a silly mistake when he kicked the opponent. And he will now not be able to play the first game in the Euros as he will be suspended.
"He was not happy because he missed some control and some passes. For this reason, I think he reacted. His reaction was to kick the opponent.
