"Fiji is the most important match of our Rugby World Cup campaign," coach Eddie Jones said in a news release.
"It's another big opportunity for our young side to keep getting better and we'll be ready on Sunday."
The experienced Nic White will instead partner flyhalf Carter Gordon at halfback with rookie Issak Fines-Leleiwasa set to win his second test cap from the bench.
Hooker Jordan Uelese has also recovered from injury and will back up starting rake David Porecki from the bench.
Ben Donaldson, man of the match against Georgia after being brought into the side primarily for his place-kicking, retains the fullback spot ahead of Andrew Kellaway.
