Wing Lee Jones will miss the rest of Scotland's summer tour after suffering a knee injury against Canada on Saturday.
Head coach Gregor Townsend has already called up Dougie Fife as cover for Jones but it has now been confirmed the Glasgow back will return home following the injury sustained during the early stages of the 48-10 win in Edmonton.
The Scots take on the USA on Saturday in Texas before travelling to Resistencia to face Argentina the following weekend.
The Scottish Rugby Union said in a statement: "Jones travelled with the squad to Houston, Texas, yesterday. Further medical assessment confirmed that he will play no further part in the tour and will return home tomorrow to the care of his club's medical team for ongoing treatment."
Edinburgh flyer Fife is due to join up with the rest of his team-mates in Houston later on Monday.
