Rio de Janeiro: Australian Olympics boss Kitty Chiller has "read the riot act" to Australia's men's sevens players after a drunken night out in Copacabana.

Fairfax Media can confirm some players staggered into the athletes' village around 9am on Saturday, much to the bemusement of team officials.

Captain Ed Jenkins, according to sources, had lost his accreditation but eventually found it and was allowed back in. It is understood an annoyed Chiller spoke to sevens team leader Luca Liussa, who was not out drinking with the players but was asked to convey her message to them.

Before these Olympics, Chiller had made a hard and fast rule about no Australians being allowed to drink alcohol in the athletes' village, nor could they be drunk around athletes who were still competing.
