England halfback Danny Care has been left out of their Six Nations training squad after being arrested for drink driving, the Rugby Football Union said on Wednesday.
It was Care's second alcohol-related incident in three weeks after he was arrested and fined for being drunk and disorderly in the early hours of December 10, following Harlequin's European Cup defeat to Toulouse.
Although Care was also fined a "substantial" amount by his club, England took no further disciplinary action on that occasion.
But after the latest incident over the festive season, England interim coach Stuart Lancaster decided to come down strongly on the 25-year-old, who missed the World Cup with a foot injury but was certain of a place in England's Six Nations plans.
The squad will be announced on January 11.
Lancaster has met with Care, told him his behaviour was not what was expected of an England player and that he will not be included in either the senior or Saxons squads.
Care's management company released a statement on their website.
"I do accept that I made a very bad decision on the evening in question and need to take the punishment that the courts hand out," Care said in the statement.
"I have decided not to contest the charge as I want to bring this to a close swiftly rather than have it hanging over my head for a year or more.
"I would stress though that at no time did I think I had drunk enough to be over the legal limit. However I should not have got into the car and have to accept the consequences of that action.
"I am devastated not to be selected for the Elite Player Squad for the Six Nations as I felt I had been playing near the top of my game with Quins."
