The Welsh wheelchair rugby league side are threatening to leave the court their final World Cup match if flash photography is banned from matches after one of their players suffered seizures.
Harry Jones has suffered seizures in two previous games at the tournament due to flash photography.
They are set to face Spain in a fifth-placed play-off match in Carcassonne, France on Thursday.
Banning flash photography from both spectators and photographers is not a competition rule at the World Cup, but Welsh management requested to tournament officials that announcements be made to all those in attendance.
"There are announcements and posters at every game regarding flash photography. We now remove the team from the pitch until it's sorted," Wales manager Mark Andrew Jones told BBC Wales.
"Harry has photo sensitive epilepsy and flash photography can affect him quite badly, to the point of a seizure.
"We made the organisers aware we would request no flash photography and the organisers have been helpful in trying to make that happen.
"If we see flash photography, the Wales team will come off the pitch until the problem is sorted.
Meanwhile, England have qualified for the World Cup final after dispatching Australia 78-36 in their semi-final in Toulouse yesterday.
They will face the winner of the semi-final between hosts France and Italy in Perpignan on Saturday (NZT).
