Nine Victorian AFL clubs have been cleared of alleged breaches of occupational health and safety but the Victorian WorkCover Authority's probe into Essendon and the AFL continues.

In June, the VWA, already investigating the Bombers over their peptides injecting program, received another complaint, calling for the remaining nine Victorian-based clubs to be investigated, with a focus on their sports science programs.

The complainant lodged paperwork with the VWA confirming Collingwood, Carlton, Geelong, Hawthorn, Melbourne, North Melbourne, Richmond, St Kilda and the Western Bulldogs as the clubs other than the Bombers that should be probed.

After an eight-month inquiry, the VWA revealed to Fairfax Media on Monday the investigation of the nine clubs, which had been represented by one law firm, was over.
