Sir Jim Ratcliffe has apologised for "offending some people" with his language after saying the UK had been "colonised by immigrants", but maintained an "open debate" on the matter was needed.
The billionaire co-owner of Manchester United had faced criticism from Sir Keir Starmer, who called his comments to Sky News on Wednesday "offensive and wrong".
On Thursday, Sir Jim said: "I am sorry that my choice of language has offended some people in the UK and Europe and caused concern but it is important to raise the issue of controlled and well-managed immigration that supports economic growth."
Sources have told BBC Sport that the FA is examining whether Ratcliffe's comments brought the game into disrepute.
Should the FA formally investigate Ratcliffe's comments and choose to charge the 73-year-old under its own rules, he could face further punishment.
