Ballymena United defender Denver Gage is at the centre of an IFA inquiry into the singing of sectarian songs at the Northern Ireland v Scotland game.
On Saturday Ballymena confirmed someone connected with the club was reported to have been involved in the incident.
A video has been posted on the internet showing fans singing the songs at the Aviva Stadium in Dublin.
BBC Sport understands Gage has been identified and could be banned from Northern Ireland home matches for life.
On Friday the Irish Football Association said it had the name of a person involved and that they would be punished if their identity was confirmed.
The association also appealed for information on all those who sang sectarian songs at the match which took place on 9 February.
The IFA has been working with the Amalgamation of Northern Ireland Supporters' Clubs and other relevant bodies to investigate the complaints.
Ballymena United's spokesman said: "It would be premature for us to add to speculation, but we wish to state that we have been in contact with, and are co-operating with, the Irish FA until such times as the allegations are confirmed or otherwise.
"Ballymena shall be making no further comment while the matter is under investigation.
Denver represented the IFA team in the regions cup a couple of years ago
