Fiji Airways Flying Fijians coach John McKee says a couple of players were sick and that is why they were sitting on the sidelines during some of the training sessions in Nadi.
McKee stresses there are no injuries in the team as the players are fit and ready for the Rugby World Cup.
He says they are not taking any risk with anyone.
He adds their focus is on the players preparation and putting on the best squad to perform in their first game against the Australians.
Fiji is pooled with Australia, Wales, Georgia and Uruguay.
Fiji will take on Australia in their first pool game at 4.45pm on the 21st of this month.
