England Under-20 international Tom Heathcote has been added to Scotland's squad ahead of their clash with Tonga.
The Bath fly-half has represented England at junior level, including at the IRB Junior World Championship, but is eligible to represent Scotland as he was born in Inverness.
"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," Heathcote told scottishrugby.org.
The 20-year-old comes into the squad after fellow number ten Ruaridh Jackson was one of five players released from the squad that faced South Africa.
"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," explained Scotland coach Andy Robinson.
