Everton right-back Lars Jacobsen will be assessed by the club's medical staff after suffering a suspected dislocated shoulder on Wednesday night.
The 28-year-old was withdrawn at half-time during Denmark's 3-2 victory over Portugal in Lisbon and will undergo tests following his return to Merseyside.
The former Nurnberg and FC Copenhagen defender has yet to make his debut for the Toffees following his free-transfer signing this summer, although he had been pencilled in to do so against Stoke this weekend.
Manager David Moyes had said of the Dane earlier this week: "Lars looks like he is in good shape at the minute and has definitely come into my thoughts for Stoke.
"He is a good footballer with a good understanding of the game and uses the ball well.
"I saw him at the weekend and he did well. We know he will give us options at right-back. We'll see how he is when he gets back."
He endured an injury-ravaged season with German club Nurnberg last term when he was limited to just seven appearances.
