Dennise Chambers has been hospitalised with an unspecified illness just a week after performing at the Festival da Jazz in St. Moritz, Switzerland.

The funk icon, who has worked with Steely Dan, Parliament-Funkadelic and Santana, is suffering liver problems, according to former bandmate Bootsy Collins.

In a post on Facebook, he writes, "Dennis Chambers is in intensive care and they're working on getting him off the respirator. They are filtering his liver, as it's not functioning well".

Chambers is best known for his work on Santana's Soul Sacrifice.

He has also toured extensively with Steely Dan, and appeared on the band's Alive in America album.

He was a member of Parliament-Funkadelic from 1978 to 1985.
