Luke Northmore will make his debut at centre as the only change to the England matchday 23 to face Argentina in the second Test in San Juan on Saturday, replacing the injured Henry Slade in the starting XV.
Coach Steve Borthwick has kept faith in the team that outclassed Argentina 35-12 in the first Test last weekend, despite the fact they are missing a host of players on tour with the British & Irish Lions in Australia.
"Saturday's match in San Juan is another great challenge," Borthwick said. "The players have trained with real focus and intensity this week, determined to keep improving in every area.
"We're expecting a tactical battle as well as a tough, physical contest, and everyone is excited for what should be a fantastic test match."
Harlequins centre Northmore, 28, will partner Seb Atkinson in the midfield, with George Ford at flyhalf and Ben Spencer in the No. 10 jersey.
The back three contains wingers Will Muir and Tom Roebuck, with Freddie Steward at fullback.
Jamie George is at hooker with props Fin Baxter and Joe Heyes either side of him, and Charlie Ewels and Alex Coles make up the second row.
Tom Willis is at No. 8, with Ben Curry and Sam Underhill the two flankers.
There is no change to the bench, retaining a 6-2 split between forwards and backs.
Ford and George will again act as co-captains.
After this weekend, England's summer tour concludes with a match against the United States in Washington D.C. on July 19.
