Vasil Lobzhanidze will become the World Cup's youngest-ever player after being named in Georgia's team to start against Tonga.
The Lelos open their campaign at Kingsholm on Saturday, and have named an experienced pack of forwards, however it is 18-year-old scrum-half Lobzhanidze who steals the headlines, breaking the record of American Thretton Palamo.
Georgia's strength will be in the pack, and Top 14 props Mikheil Nariashvili and Davit Zirakashvili line up alongside former Toulouse hooker Jaba Bregvadze in the front row.
Toulon's Konstantin Mikautadze gets the nod in the second row, next to Giorgi Nemsadze, while Viktor Kolelishvili and Mamuka Gorgodze provide plenty of top flight experience in the back row.
Lobzhanidze combines with Lasha Malaguradze in the half-backs, while veteran full-back Merab Kvirikashvili will start in his fourth World Cup.
