Saints have signed Samoa full-back Fa’atoina Autagavaia as injury dispensation for Ben Foden.
The 25-year-old, who has eight caps to his name, will link up with countrymen George Pisi, Ken Pisi and Kahn Fotuali’i at Franklin’s Gardens.
Foden and Kiwi utility back James Wilson are currently sidelined with knee and calf injuries respectively, leaving wing Ken Pisi to fill the No.15 shirt.
But Autagavaia, who scored a try for Samoa against Wales at the Millennium Stadium last November and has recently been playing for Northland in the ITM Cup, will provide competition.
And Saints director of rugby Jim Mallinder said: “Fa’atoina has shown over the past 18 months that he has the ability to succeed at international level.
“We are confident that he’ll be able to fit in at Franklin’s Gardens, especially alongside the Pisi brothers and Kahn Fotuali’i.
“With Ben Foden and James Wilson both out of action we’re a bit light at full back, so Fa’atoina will add to our strength in depth in what is a crucial position.”
