Bosnich was found guilty by the FA
The Football Association has given goalkeeper Mark Bosnich a nine-month ban for failing a drug test.
The Australian was found guilty after testing positive for cocaine in 2002.
The player, 31, had claimed his drink had been spiked with the drug while out, and intends to appeal the FA decision.
An FA commission ruled after a two-day hearing that he was guilty of charges of improper conduct and breaching their doping control regulations.

The Australian will nevertheless not face the maximum penalty of a two-year suspension, with his nine-month ban backdated to start from 23 December 2002, when a temporary worldwide restriction was first enforced.
That means the former Aston Villa and Manchester United goalkeeper could start playing again
before the end of September.
Bosnich, who has had his contract terminated by Chelsea, was not fined, but he must pay the costs of the FA commission up to a maximum of £10,000.
The Australian is already contesting a
Premier League ruling that upheld Chelsea's decision to dismiss him.
Bosnich joined Chelsea in 2001 on a free transfer from
Manchester United but made only seven appearances for the London club.
Chairman of the Professional Footballers' Association Gordon Taylor believes the
goalkeeper could rebuild his career.
"It may well have been worse (Bosnich could have been banned for two years) and while it is damaging to his career, it does not mean to say his career is
over," said Taylor.
