The club confirmed the news following this afternoon's 4-2 win over Arsenal in the Barclays Premier League.

The Brazilian, City's record signing, suffered his injury on international duty.

Robinho sustained his injury during Brazil's World Cup qualifying win over Argentina last Saturday.

City boss Mark Hughes indicated this week that he did not think there was any extensive damage to Robinho, and at one stage he was given a chance of facing Arsenal.

The Brazilian was sent for a scan to check for damage to his inflamed ankle, which produced the unwelcome result, ruling Robinho out until early next month.
