There is much debate over whether midfielder Steven Gerrard should be given a pain-killing injection to enable him to play against Israel with a broken toe.
But Richards admits he would have no hesitation going under the needle if he was in a similar position to enable him to play for his country.
He said: "Would I have a pain-killing injection to play? Yes, for your country, you've got to haven't you? Previous players have before.
"You would do anything to play for your country. I certainly would."
