Inter Milan could be without top scorer Mauro Icardi for up to a month after it was confirmed that he had strained his lateral collateral ligament.
Icardi, who has scored 12 goals in Serie A, limped out of the weekend's 2-1 win over Bologna after getting his leg trapped under his body as he lunged for a cross.
It was initially feared that he could have torn ligaments, but a scan on Monday revealed the strain.

The injury means he will miss Inter's trip to Roma on Sunday, and a tweet from the Serie A club said the situation "will be re-evaluated in the coming days."
Such an injury usually takes up to a month to recover from, meaning Icardi may not be back until Inter face Napoli on April 17.
Inter trail Roma by five points in the race to finish third and qualify for the Champions League next season.
