FA Chairman Greg Dyke said: "Rape and sexual violence are abhorrent and unacceptable. This cannot be overstated.
"We have reviewed the Ched Evans case in some detail at The FA and we have examined both the legal requirements and our rules and regulations and there is no basis for us to intervene directly in this particular case.
"That said, it is important that we continue to look at the issue of behaviour and attitudes within football, and recognise the unique privileges and responsibilities that come with being a participating member of the national game.
"I would encourage the game to consider and discuss this matter and the prospect for future guidelines or codes of conduct. The FA will certainly be considering it in line with our own ongoing review of what constitutes public or private communications and behaviour."
