Jane's Addiction have been forced to cancel their Australian tour after drummer Stephen Perkins was hospitalised.

The sticksman was admitted to the Infectious Disease Ward of the Cedars-Sinai Hospital in Los Angeles on Saturday after being struck down by a mystery illness.

He still remains at the hospital, prompting the band to axe the dates Down Under.

A statement from the band posted on their website reads: "Doctors expect to keep (Perkins) there for the next few days for further diagnosis and observation while anti-biotic treatment continues. Fans are being asked not to worry as a full recovery is expected over the next few weeks.

"The reformed original line-up of Jane's Addiction had been on their first world tour in over 17 years and had just returned to Los Angeles from a successful European leg when the mysterious infection was discovered after Perkins noticed severe swelling and pain building in his elbow.

"Regretfully the group's Australian tour, due to start on Saturday, is forced to be cancelled at this time."

Singer Perry Farrell ensured fans that they're still hoping to reschedule the jaunt.
