The match in Seville is the first between the two nations in Spain since the clash at Real Madrid's Bernabeu stadium in November 2004 when England's black players were abused by large sections of the crowd.
"If things got as bad as last time the referee would have to make a decision," Terry told a news conference. "If he decided to lead the teams off we would support that."
Terry said the players had not discussed the issue but they had been briefed about it by press officers from the Spanish soccer federation (RFEF).
At a separate news conference on Tuesday, an RFEF spokeswoman intervened to prevent Spain captain Iker Casillas and players Andres Iniesta and Carlos Marchena answering a question about the possibility of racism in the stadium.
