Scotland secured their first win in 2019 Six Nations group with a 26-11 triumph over France in Paris on Saturday.
The Murrayfield side deservedly went into the game on the back of a scintillating display against Australia, with wingers Finn Russell and Huw Jones both scoring one try apiece.
Jones had a goal-kick conversion disallowed by the TMO but still crossed for his second try of the campaign.
The hosts were also docked 10 points after French officials refused to stamp their boot onto a ball during a ruck in the build-up to the Scots’ sixth try.
However, the result keeps Scotland third in Pool A with just one match left against Italy.
