Chris Cornell has cancelled his Download Festival appearance as well as the rest of his European tour.
The singer songwriter was scheduled to appear on the main stage on the Sunday night but has had to pull out citing recording commitments.
In a statement the singer said: "Due to an extended recording schedule, I will be able to perform in front of my European fans a few months later than expected. With that said, I plan on touring extensively through Europe and the rest of the world through 2008-2009."
Download organisers have yet to say whether or not they will replace the ex-Audioslave guitarist at the festival.
