Ashley Young is unsure how England's players would react if they were racially abused during the European Championship.
The Manchester United star backed UEFA to deal with any incidents that might occur in Poland and Ukraine but would not be drawn on whether he or his team-mates would walk off the field in protest.
Euro 2012 only began on Friday night but there have already been two alleged episodes of monkey chanting at black players.
Young was the victim of identical abuse during England's qualifying match in Bulgaria in September, something which saw the Bulgarian Footballing Union fined £34,000.
UEFA have vowed to adopt a "zero-tolerance" approach to racism at this summer's finals, with referees having the power to abandon games if necessary.
But UEFA president Michel Platini also warned on Wednesday that any player who walked off the pitch in protest at racist abuse would be yellow-carded.
Asked if England might walk off, Young said: "Who knows? Hopefully, it doesn't happen and UEFA deal with it before a decision has to be made.
"You don't want to put up with things like that but it is for UEFA to deal with.
"I am sure they would do in the right way. We will see what happens.
"If it happens, I am not too sure what we would do."
UEFA acknowledged on Friday Holland's black players were the victims of monkey chants during a training session on Wednesday, while it emerged on Saturday afternoon that Czech Republic defender Theodor Gebre Selassie suffered similar abuse in his country's defeat to Russia on Friday night.
"There is talk that it happened at the Dutch training session, which is disappointing," said Young, before recalling his own experience in Sofia.
"It is something that you try to block out. The referee was made aware of it in that game. The FA (Football Association) took it into their hands afterwards."
There have been fears about racism in Poland and Ukraine ever since they were named co-hosts of Euro 2012 and the families of black England stars Theo Walcott and Alex Oxlade-Chamberlain have refused to travel to the tournament for that reason.
Asked about his own family's plans, Young said: "I am not going to comment on that. It is a private matter."
