Import pair join Saints
Northampton have signed South African forwards Juandre Kruger and Regardt Dreyer - and they will arrive when their Currie Cup commitments are over.
Kruger, 23, a lock or back row, joins from the Blue Bulls and Dreyer, 25, a loosehead prop, plays for Griquas.
Saints director of rugby Jim Mallinder said: "They will add to our strength in depth in two crucial positions, something we feel is necessary."
