AC Milan forward Robinho could reportedly miss the start of the Italian season with a groin injury.
The Brazilian, who recently signed a new deal at the San Siro, suffered the knock in their 2-1 win over Valencia at the Mestalla on Saturday.
According to reports in the Italian media, the injury could keep the former Real Madrid forward out for "several weeks", which would also rule him out of the Champions League playoff tie.
Robinho also had a penalty saved in the victory over Valencia.
