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."

Skipper for the day Aled Thomas praised his Gloucester team mates, especially the younger ones, for the way they took on a tough Ospreys outfit and emerged victorious in the LV= Cup on Saturday afternoon.
Gloucester will field a reshuffled side against the Ospreys in the LV= Cup this weekend, but Backs & Attack Coach Nick Walshe stressed that it's a great opportunity for everyone on duty on Saturday and that maintaining the recent winning run is very important.
Skipper Billy Twelvetrees told GRTV after the win in Brive that the game could have been a tough one to get up for, but that his Gloucester team mates did themselves proud on the night and got a big result.
Reflecting on the 31-20 victory in Brive on Thursday evening, Director of Rugby David Humphreys said that clinching a home European Rugby Challenge Cup quarter-final was the overall aim and duly achieved.
Gloucester Rugby and the Ospreys shared seven tries and 57 points in the LV= Cup at Kingsholm on Saturday. The Cherry and Whites came out on top and the club photographer captured the best of the action.
