London Irish duo Paul Hodgson and David Paice are given the nod over Micky Young and Joe Gray at scrum-half and hooker respectively.
The Saxons opened their Churchill Cup defence with a record 87-8 victory over the USA, who also lost 44-13 to Tonga on Wednesday.
The winners will meet Canada in the final in Worcester on June 18.
Head coach Stuart Lancaster said: "We've rotated our squad for this game to give other players opportunities to demonstrate their abilities.
"Tonga had a very good win against what was probably a stronger USA side than the one we faced and we're very aware of the physicality they'll bring on Sunday."
