Benhard Janse van Rensburg, Charlie Bracken and Archie McParland have all been named in England's training camp ahead of the inaugural Nations Championship.
Bristol centre Van Rensburg will complete his five-year eligibility period on July 8 - notably, four days after England's opening match against South Africa - and is seen as a potentially key midfield option in the run up to the 2027 World Cup.
The Pretoria-born centre, who joined London Irish in 2021, will qualify through residency after the RFU successfully lobbied World Rugby to bring his eligibility date forward from November. He had previously made one substitute appearance for South Africa under-20s in 2016.
Bracken, son of former England scrum-half Kyran, has also been given his first call-up by Steve Borthwick and will join up with team-mates at the Performance Centre at Pennyhill Park until Wednesday.
McParland made his Saints debut as a 17-year-old against London Irish in September 2022.
The squad also features an international return for highly-rated lock George Martin, who gets a call-up for the first time since February 2025 having suffered a combination of knee and shoulder injuries that had kept him out of action for 14 months.
Winger Noah Caluori, who was previously selected in the squad for last autumn's internationals, has scored tries for fun in all competitions this season for Saracens as well also playing in the Championship under dual registration for Ampthill.
Notable absentees from Borthwick's selection include Bath pair Ollie Lawrence and Henry Arundell. The centre and winger have both been omitted on form rather than fitness.
Van Rensburg will be eligible after England's opening Nations Championship fixture against his native country in Johannesburg on Saturday July 4 and could make his debut against Fiji at Everton's Hill Dickinson Stadium on Saturday July 11.
Your Site News' James Cole:
Van Rensburg's inclusion in this England training squad is a really interesting and exciting selection.
"He's six foot tall, he's 17 stone, he's a very imposing physical ball carrier, he's also got a really good offloading game too and defensively solid.
"We thought he would be available, become available, for Steve Borthwick in the autumn, but actually he's going to be available sooner, this summer.
"He won't be available for the South Africa game which is in Johannesburg on July the 4th but he will be for the games that follow it against Fiji and Argentina and the fact he's in this squad suggests Borthwick has every intention of blooding him.
"He has that typically South African attribute of immense physicality and for that reason is a really exciting prospect.
"There are a few surprise or notable omissions in this squad too. Ollie Lawrence, a man who's been the mainstay in England's midfield for a number of years now, is not included.
"That is a surprise because he's not injured, he's not been included on form and neither has his Bath teammate Henry Arundel despite scoring nine tries in his last seven games."
