The Lorraine outfit had scheduled to visit England at the start of August for friendly matches against West Brom and Crystal Palace, but have been put off following a number of outbreaks of swine flu in the country.
"The Nancy staff have judged it reasonable not to take the slightest risk a week before the start of the Ligue 1 championship and have preferred instead to arrange another match, against Auxerre on Saturday, August 1," read a Nancy statement.
Nancy had been due to play West Brom on August 1 and Palace the following day.
