The Republic of Ireland team have apologised following reports of players singing a pro-IRA chant in the dressing room following their 1-0 win over Scotland on Tuesday night.
The win secured Vera Pauw's squad qualification for next year's World Cup, marking their first ever major tournament.
Footage circulating on social media shows players in the dressing room after the game, chanting 'Up the RA'.
On Wednesday morning, the Football Association of Ireland (FAI) released a statement explaining the team have "apologised for any offence caused by a song sung by players in the Ireland dressing room" after the game.
The statement quotes Pauw, who said: "We apologise from the bottom of our hearts to anyone who has been offended by the content of the post-match celebrations after we had just qualified for the World Cup."
The manager added they will review the matter with the players, and "remind them of their responsibilities in this regard".
"I have spoken with players this morning and we are sorry collectively for any hurt caused, there can be no excuse for that," Pauw said.
