The Football Association has written to David Beckham asking for an explanation about the controversy surrounding his yellow card against Wales.
England captain Beckham admitted he got booked on purpose in the knowledge he would miss the next game through an injury incurred in the match.
Beckham has since apologised but the FA wants detailed 'observations' from the Real Madrid midfielder.
It has given him until 22 October to respond to their request.
Beckham fouled Ben Thatcher so he would be suspended against Azerbaijan - knowing he was already injured.
And, in a statement issued on Friday, the FA has asked Beckham for his observations on:
The incident involving Ben Thatcher during last Saturday's World Cup qualifying match against Wales, which resulted in him receiving a yellow card.
- The motivation which led to him making the challenge which incurred a caution.
- Subsequent comments attributed to him which were published in a national newspaper on Tuesday October 12th.
FA chairman Geoff Thompson earlier told BBC Radio Five Live "the issue will be dealt with in the proper way."
Asked whether Beckham could carry on as captain he added: "Of course he can. The captain has possibly made an error of judgement but he has apologised for it.
"It's a good thing that he's given that apology. This is a matter that will take its own course."
Beckham revealed on Wednesday he made the admission after negative coverage of him following the Wales game but said that was a bad decision.
He said: "In an interview I was asked a question and made a frank and honest admission to counter the negative speculation.
"I now know that was wrong and apologise to the Football Association, the England manager, my team-mates and all England fans for this.
"I know that, as captain, you are in a privileged position and must always abide by Fifa's code of fair play, something which I have always done throughout my career.
"On this occasion, I made a mistake."
