Wigan Athletic chairman Dave Whelan has met a deadline to give the Football Association his "observations" on his recent comments that were accused of being racist and anti-Semitic.
The 78-year-old had until 6pm this evening to offer his thoughts in a document to English football's governing body.
Mr Whelan apologised for any offence caused by his comments in a newspaper interview.
Since learning he is being investigated by the FA, he has threatened to resign his position if found guilty of making racist remarks.
The FA said it will now "consider" his observations as part of the ongoing investigation.
The Football Association has issued an apology after a section of England's supporters chanted an anti-IRA song throughout the first-half of Tuesday's international in Scotland.
A spokesman for the FA said: “We apologise for any offence caused by a section of the England support at the match with Scotland. The FA does not condone inappropriate and offensive chanting and intends to meet with supporters’ groups to discuss the wider issues.
“We have consistently urged supporters to show respect and not to chant songs that could be regarded as insulting to others - particularly from a religious or political perspective.
“With regard to the supporters’ band, there was contact during the match once the situation became clear. This is consistent with regular dialogue that takes place between the band and The FA.
“In also apologising, the band have given an explanation and confirmed they in no way endorse the chanting that occurred.”?
The leader of England's band was "unaware" of anti-IRA chants from England fans inside Celtic Park on Tuesday.
The FA were forced to contact the band during last night's international friendly between Scotland and England to prevent them from assisting with the offensive chant.
John Hemmingham, who formed England's band 21 years ago, told Press Assocation:
"We were absolutely not aware of it. All the fans around us were singing ’Follow England Away’. It was only when a band member saw on Twitter that some people were saying we were playing anti-IRA songs that we became aware. Then we immediately stopped and played something else.”
England will play glamour friendlies against world champions Germany and France in the build-up to Euro 2016.
The Football Association announced on Wednesday that the Three Lions will host France on November 17 next year, and it also confirmed England will play a friendly in Germany in March 2016.
Negotiations are also under way regarding potential pre-Euro 2016 friendlies against Holland and Spain.
The FA has already announced fixtures against Italy for March next year and a fixture against the Republic of Ireland at Dublin's Aviva Stadium on June 7.
England manager Roy Hodgson admits to being unhappy over Wembley being used for NFL days before his side play Slovenia there.
Jacksonville Jaguars play the Dallas Cowboys on Sunday, with Hodgson's men in action on the following Saturday.
The former Liverpool boss is deeply concerned by the effect the American football match will have on the surface.
"I can't pretend that is something that makes me leap for joy," Hodgson said.
"If I was asked if it was a good thing or not, I would have to say not.
"I don't really think you could expect me to say 'excellent, delighted, well done'.
"The pitch, unfortunately, is not in the best of nick anyway, which we're all a bit unhappy with."

The prospect of an NFL franchise to be based at London's Wembley Stadium will be explored in detail, the sport's UK chief has said.
England football matches could be taken around the country again from 2018 if the Football Association secures the NFL franchise for Wembley.
Alistair Kirkwood, managing director of NFL UK, told BBC Radio Five Live: "Moving from one game to three games in a couple of years is a sign of real momentum and fan growth.
"We are going to have a look at seeing if we can grow from that over the next couple of years and see where we go from there.
"We're very interested in exploring the idea of a British-based franchise and seeing if we can pull it off. That's the way of making our sport much more mainstream."
