England will enter their crucial World Cup clash with Argentina boosted by the return of Mako Vunipola and Jack Nowell from the bench.

Vunipola and Nowell missed the Pool C victories over Tonga and USA because of respective hamstring and ankle injuries but have been passed fit for the first major test of the group phase.

The starting XV shows only one change to the side that secured a bonus point in the Sapporo opener with George Kruis replacing Courtney Lawes in the second row.

England are guaranteed passage into the quarter-final if they topple Argentina seven days before they lock horns with Six Nations rivals France.

"Argentina is a completely different team from others we have played so far in the pool stages and are always about the physical contest," Jones said.

"This week it's about getting our game right, our set piece in a good place and making sure defensively we are organised and ready to find ways to score points against them."
