Steve Borthwick has named his England team to play Argentina on Saturday 12 July, live on Sky Sports, making just one change to his side.
Luke Northmore is set to make his first start in an England shirt at centre with the rest of the team remaining unchanged. Northmore replaces Henry Slade, who was confirmed as out for the remainder of the tour following a hand injury.
The replacement bench subsequently remains the same and England have retained a 6-2 split between forwards and backs.

"Saturday's match in San Juan is another great challenge," said Borthwick.
"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."
