Manchester City forward Carlos Tevez will miss Saturday's Barclays Premier League game against Arsenal, manager Mark Hughes has confirmed.
The 25-year-old picked a knee injury while on international duty with Argentina, but City hope he will ready to face Manchester United the following weekend.
"Our doctor has spoken to the Argentine medical people and the feeling is that he is out for the weekend so he will not play against Arsenal," Hughes told www.mcfc.co.uk.
"The hope is that he will be okay for the derby, but we will have to determine that when he comes back.
"He is staying with the national squad because he needs acute treatment at the early stage of the injury, which is what he can get now.
"Flying him back quickly might compromise the injury, so he will be back towards the end of the week so we can assess him and hopefully get him ready for the United game."
Robinho, who faced Tevez in Brazil's 3-1 win over Argentina on Saturday, also has a slight knock.
"It's a different situation with Robi," said Hughes. "It's an old injury that he aggravated last year, just above his ankle.
"We are going to get him back as soon as possible, the hope is that he will be an option for the weekend."
City are fourth in the Premier League having won all three of their fixtures so far this season.
