Scotland head coach Steve Clarke is “100% worried” about Billy Gilmour after the midfielder came off injured during the 4-1 friendly win over Curacao.
The Napoli player, 24, will have a scan later on Saturday and Clarke says he is “hoping and praying he’ll be on the plane” when the Scots fly to the United States on Sunday.
Gilmour started at Hampden but was withdrawn after pulling up with a knee issue.
His replacement, Findlay Curtis, scored Scotland’s first-half leveller before Lawrence Shankland’s double after the break and a late Ryan Christie penalty.
