Sydney - Former Adelaide United striker Ken Ilso Larsen was banned Friday for two years by Australian authorities after testing positive for cocaine.
The presence of benzoylecgonine - the drug's main byproduct - was detected during a test in January.
Larsen was provisionally suspended in March while an investigation was conducted by the Australian Sports Anti-Doping Authority.
The Dane has since left the club and was Friday slapped with a lengthy ban.
"Football Federation Australia has imposed a period of suspension of two years, to run from the date of Mr Larsen's provisional suspension," the governing body said.
The 32-year-old joined Adelaide last year
