Manchester City boss Mark Hughes has confirmed Craig Bellamy faces a spell on the sidelines through injury.
Bellamy picked up a knee injury during Sunday's 1-0 defeat at former club West Ham.
The Welshman has been ruled out of Wednesday's clash with Aston Villa along with team-mate Robinho after he also picked up a knock at Upton Park.
Bellamy has been sent for scans on the injury and Hughes admits the striker will be missing for two weeks at least.
Hughes said: "Craig Bellamy and Robinho won't be fit [to face Aston Villa].
"Craig got examined yesterday and he is having a scan today to allow the injury to settle down for 48 hours and those scans will be read.
"It is not an old injury. I saw it reported it was a reoccurrence of an injury he had before, it is not, it is a new injury.
"He has torn some fibres in his knee and obviously the extent of the injury will be shown in the scans.
"We just hope the best case scenario is probably two to three weeks."
Hughes insists Robinho's ankle injury is not so serious and that he should return for the Uefa Cup clash with Aalborg next week.
"Robbie got a similar injury to that he had against Arsenal," added Hughes. "Obviously he is not going to be available tomorrow unfortunately, but we are hopeful he will be okay for Aalborg."
