Dylan Hartley, Courtney Lawes and Tom Wood will be the Saints representatives in England’s 23-man squad to face New Zealand at Twickenham on Saturday.
But Lee Dickson and Calum Clark will not return to Pennyhill Park on Wednesday night to prepare for the game as they have been sent back to Franklin’s Gardens.
Luther Burrell (hand) and Stephen Myler (hamstring strain) are ruled out of the Test against the All Blacks.
Alex Waller and Ben Foden had trained with England as cover last week, but have since returned to Saints.
The Red Rose players who have come back to Northampton could play a part in Friday’s LV= Cup game at Scarlets, but Burrell and Myler are unavailable.
“Luther has seen the specialist and, while the news is positive that he could be available later in the series, he will stay with the Saints medical team this week,” said England head coach Stuart Lancaster.
“We will look to bring him into camp further down the line.”
