Namibia head coach Phil Davies has made eight changes to his starting XV for Tuesday's Pool C clash with Tonga in Exeter.
In the backline, Exeter Chiefs fullback Chrysander Botha will wear the number 15 jersey while Johan Tromp, who started in that position against New Zealand, moves to the right wing where he replaces David Philander.
Danie van Wyk comes in at outside centre for JC Greyling while Russell van Wyk starts on the left win in place of Conrad Marais and Eneill Buitendag is preferred to Eugene Jantjies at scrum-half.
Up front, Renaldo Bothma replaces Leneve Damens at number eight and Rohan Kitshoff comes in for Tinus du Plessis on the flank where he will partner the team's captain Jacques Burger.
The final changes sees Janco Venter taking over from Pieter-Jan van Lill at lock and Casper Viviers replaces Jaco Engels at loosehead prop.
