The Vodafone Fiji 15s team now has a kava and alcohol ban in place.
Coach, John McKee says this will stay in place throughout the tournament.
McKee says off-the-field discipline is a major focus as these players are role models and are representing the people of Fiji.
Fiji will be the home nation in the opening match against England in Twickenham at 7am on the 19th of September.
Fiji won the coin toss and has opted to wear their traditional white jersey for the match while England will have to wear their away jersey.
