England Under 20s have made 12 changes for their final IRB Junior World Championship pool game against Argentina, and fly half Billy Burns is named amongst the replacements whereas Ross Moriarty is rested.
Just Nick Tompkins, Henry Purdy and Charlie Ewels retain their places from the 38-24 victory against Australia.
There are first U20 starts for Biyi Alo, Jordan Onojaife, Hayden Thompson-Stringer and Cameron Neild, while Tom Stephenson comes back into the side after helping Northampton Saints to Premiership victory.
Head Coach Nick Walshe said: "The great thing about our squad is that we have real strength in depth. There are a few lads desperate to make an impression and this is a great opportunity for them to perform.
"Argentina will be physical and they'll provide a real test, but we've had a good few days since the Australia game, have recovered well and we'll be ready for a tough match."
