James McClean has received further support from Kick It Out, the group tackling racism and discrimination in football, after it said he received "anti-Irish and sectarian abuse" last weekend.
McClean was part of the Stoke City side that drew 0-0 with Millwall on Saturday in the Championship at the Bet365 Stadium.
The body has reported the matter to the FA.
Kick It Out said: "James McClean was once again subjected to disgraceful anti-Irish and sectarian abuse this weekend.
"We have informed the FA so they can investigate but we reiterate - the abuse he continues to receive is absolutely unacceptable and shames our game.
"We have been in constant contact with Stoke City and James, as we continue to offer our full support.
"Greatest action must be taken by the authorities to safeguard his and his family's wellbeing, because the current situation cannot continue."
McClean's club Stoke have previously condemned "discriminatory" chants aimed at the Republic of Ireland international and offered him their full support.
McClean has been the target of chants in Championship games at Huddersfield and Barnsley this season, with the latter charged by the English FA in connection with allegations of sectarian abuse.
The FA has yet to comment.
