England Under-20 international Tom Heathcote has joined up with the Scotland squad ahead of the EMC Test against Tonga.
The Bath stand-off played for England in the IRB Junior World Championship this summer but was born in Inverness. The 20-year-old, who has Heineken Cup experience with Bath, came in after Ruaridh Jackson was one of five players released from the squad.
Heathcote told www.scottishrugby.org: "I am delighted to be called up to the Scotland squad. I've always known I was eligible to play for Scotland and I'm grateful to be given this opportunity."
Scotland head coach Andy Robinson added: "Tom has worked his way into the Bath first team squad from the academy and we've been monitoring his progress for the last couple of years."
Jackson was the only released player who featured in Saturday's 21-10 defeat by South Africa.
The stand-off will prepare for Glasgow's RaboDirect Pro12 clash with Leinster on Friday along with Alex Dunbar and Tom Ryder.
Edinburgh wing Lee Jones joined prop Allan Jacobsen, who earlier announced his retirement from international rugby, in staying in the capital as the Scotland squad travelled to Aberdeen to prepare for the Pittodrie clash.
Robinson will name his team on Wednesday as Scotland look to bounce back from defeats by the Springboks and New Zealand.
