New Zealand refused to appear for the second half of a friendly against Qatar in Austria on Monday after New Zealand said a Qatari player called All Whites defender Michael Boxall a racial epithet.

It was one of two such incidents in Austria on Monday, with Ireland's football association saying its under-21 team had abandoned a match against Kuwait's Olympic side after a Kuwaiti player used racist language toward an Irish substitute.

"A Qatari player used a racial slur towards All Whites defender Michael Boxall after a confrontation between the two players. The racial slur was heard by several New Zealand players, including Boxall," New Zealand Football (NZF), the country's governing soccer body, said in a statement.

New Zealand-born Boxall has Samoan heritage. New Zealand was leading 1-0 after a Marko Stamenic goal in the 16th minute. The incident occurred just before halftime. Referee Manuel Schuttengruber had a long discussion with New Zealand captain Joe Bell and soon after blew for the interval.

"No official action was taken so the team have agreed not to come out for the second half of the match," NZF said on social media.

New Zealand Football CEO Andrew Pragnell said the New Zealand players agreed collectively to abandon the game and the governing body fully supported them.

"There is no room for racism in football," he said.

Qatar coach Carlos Queiroz said his team stood by its player.

"Apparently two players exchanged words, and we don't know who was first, who was second, it's only between them," the Portuguese coach told Al-kass Sports Channels. "The New Zealand players decided to support their teammate and we also decided to support our player.

"Let the football authorities make the decision about what happened here."

The Qatar FA said on its Twitter feed that New Zealand had withdrawn from the friendly, without giving any further details.

The Football Association of Ireland said its under-21 international was abandoned after a "racist remark" by a Kuwaiti player.

"The FAI does not tolerate any racism towards any of our players or staff and will be reporting this serious matter to FIFA and UEFA," the FAI said on social media.

Kuwait's FA disputed the FAI's claim, writing on social media: "Kuwait Football Association ... categorically rejects such accusations.

"The match did not reach completion due to excessive roughness and tension between the players. The match was stopped by the referee in the 70th minute to protect the players from potential injuries."

Ireland was leading 3-0 when the match was stopped.

Racism has dominated football headlines in recent months.

FIFA president Gianni Infantino announced an anti-racism committee led by Real Madrid forward Vinicius Junior, who has been the victim of racist abuse in Spain's La Liga.
