Artur Boruc is one of another four Saints players to have been selected for international games that will take place in early September.
Emmanuel Mayuka, Dejan Lovren and Lloyd Isgrove have also been called up by their respective countries for matches over the coming fortnight.
The quartet take Saints' list of international participants to ten, following on from call-ups for Rickie Lambert (England), Gastón Ramírez (Uruguay), Steven Davis (Northern Ireland), Luke Shaw, James Ward-Prowse (both England Under-21s) and Calum Chambers (England Under-19s).
Boruc and Poland have two 2014 FIFA World Cup qualifiers to look forward to. First they host Montenegro on Friday 6th September, before travelling to play San Marino four days later.
Mayuka – who scored his first competitive goal for Saints last night – is in the Zambia squad for their World Cup qualifier in Ghana next Friday.
Croatia have named Lovren in their squad for a qualifier against neighbours Serbia in Belgrade next Friday and the subsequent away friendly against South Korea on 10th September.
Isgrove is in the Wales Under-21 squad for their 2015 UEFA European U21 Championship away qualifiers against San Marino in Serravale and Moldova in Chișinău.
Furthermore, youngsters Sam Gallagher and Matt Targett are in the Scotland Under-19 party that will face Iceland in a friendly next Tuesday evening.
