Former Bath lock Justin Harrison has been suspended for eight months after admitting three drug-related charges at a private Rugby Football Union disciplinary hearing.

Harrison, 35, was suspended by RFU disciplinary officer Judge Jeff Blackett for "actions which are prejudicial to the interests of the game".

Harrison admitted taking a prohibited substance during an end-of-season celebration in London and subsequently failing to submit to a drugs test.

The former Australia international also admitted to shouting: "Class A, it's OK, everyone's doing it" in the vicinity of Bath's academy players.

The suspension was back-dated to May 14, the day Harrison resigned from Bath and withdrew from the Barbarians tour.

He is banned from playing and coaching rugby until January 13, 2010.
