The majority of the team play for Fijian Drua in Super Rugby Pacific, but Byrne has a smattering of European-based players available to add considerable experience.
New Zealand-born Muntz forms a halfback pairing with scrumhalf Simione Kuruvoli and they will look to fire a big backline full of hard-running ball carriers that will test England’s defence.
Racing 92 centre Josua Tuisova and Kalaveti Ravouvou from Bristol Bears are the midfield pairing, while the back three is made up of Toulon wing Jiuta Wainiqolo, Selestino Ravutaumada, and Bordeaux fullback Salesi Rayasi.
Hooker Tevita Ikanivere will have Saracens prop Eroni Mawi and Mesake Doge either side of him, while Isoa Nasilasila and Temo Mayanavanua make up the second row.
Kitione Salawa and Elia Canakaivata are the two flankers, with Bristol Bears’ Viliame Mata at number eight.
Fiji are playing a first test since they defeated Japan 33-27 to lift the Pacific Nations Cup in September.
The islanders won 30-22 in their last visit to Twickenham in 2023, but have lost their eight other meetings with England.
