Georgia’s 18-year-old scrum-half Vasil Lobzhanidze will become the youngest player in Rugby World Cup history after being selected to play Tonga.
Lobzhanidze, who will not turn 19 until mid-October, is set to beat the record currently held by Thretton Palamo.
The American was 19 years old and eight days when he played against South Africa in 2007.
Georgia and Tonga, who are in Pool C along with New Zealand, play each in Gloucester on Saturday (12:00 BST).
