Sevilla will be without the services of French midfielder Steven N'Zonzi for Tuesday's European Super Cup against Barcelona.
The 26-year-old had been expected to make his official debut for the Europa League winners in this week's showpiece event in Georgia.
However, the midfielder, who joined Sevilla from Stoke City this summer, did not make the trip with the rest of his teammates on Monday after picking up a stomach bug over the weekend.
Adil Rami and Timothee Kolodziejczak are also both believed to be suffering from the same illness, but did make the trip from Seville.
Sevilla beat Barcelona 3-0 in the 2006 European Super Cup.
