The band is still to embark upon a tour of the UK next month
A concert by Oasis at Cornwall's Eden Project has been postponed because of injuries Noel Gallagher received when a concert-goer attacked him in Canada.
Gallagher damaged three ribs in Toronto earlier this month when he fell on some stage equipment after a man invaded the stage and pushed him over.
The Eden concert was due to be held this Saturday.
Eden said ticket holders were advised to keep their tickets and await further announcements.
Shows in Cologne and Paris over the following two days have also been postponed.
Eden Creative Director Peter Hampel said: "We are sorry to hear that Noel's injuries mean that he will not be well enough for the band to perform on Saturday and we wish him a speedy recovery.
"We share fans' disappointment at the latest news. We are now talking to the band's management about rescheduling the concert."
In a statement, the band's management said: "Oasis are being forced to postpone three shows as a result of the injuries Noel sustained when he was attacked on stage in Toronto.
"A CT scan has now revealed that Noel suffered three broken and dislodged ribs in the attack and he has been advised by his doctor that he will not be able to perform for at least another week."
The other affected shows should have been at the Gloria Theatre in Cologne on 29 September and Bataclan in Paris on 30 September.
The band's management said the Oasis UK Arena Tour, which is due to begin on 7 October, would be going ahead as planned.
