Bristol Bears lock Chris Vui has signed a new contract that keeps him at Ashton Gate until the summer of 2022.
The Samoa captain, 25, joined from Worcester last year and helped the club win promotion to the Premiership.
This season, he has made four top-flight appearances so far.
“Being the youngest captain in world rugby is testament to his leadership and attitude – I’m pleased he sees his continued development here,” said Bristol head coach Pat Lam said.
