John Stones is set for a spell on the sidelines after Inter confirmed the England centre-back has sustained a strain in his left thigh.
Stones suffers thigh injury on first Inter start
Inter may have to do without John Stones for a number of weeks after he injured his thigh playing against Udinese on Monday.
The experienced defender was making his first start for the Nerazzurri in Monday's contest with Udinese, which Inter won 5-3 in an eight-goal thriller.
However, the former Manchester City defender went off in the 62nd minute, with Benjamin Pavard coming on his place.
An official Inter statement read: "John Stones underwent clinical and diagnostic tests this morning at the Istituto Humanitas in Rozzano.
"The tests revealed a muscle strain to the flexor muscles in his left thigh.
"His condition will be reassessed over the coming days."
While Inter did not put a timeframe on his recovery, some reports are suggesting that Stone will be sidelined for at least a month.
If that were to be the case, it may not be overly negative news for Inter, who visit Roma on Saturday but then have a three-week break due to the international window.
It is worse news for England, though, who would be without Stones for the start of their Nations League campaign.
