Claus Lundekvam is poised to make a surprise appearance on Saints' Swedish tour.
The centre half was expected to miss the three-game tour following exploratory key-hole surgery to discover the cause of sever stomach pains.
He was rushed to hospital from the club's Scottish training camp last week with suspected appendicitis which turned out to be infected lymph glands.
Also on board this morning's flight were Jason Dodd and Rory Delap, who both missed the FA Cup final through injury.
Marian Pahars saw a specialist in Bristol last night hoping for the all-clear to join up with the squad.
Pahars has been running strongly following a third ankle operation but he is still far from match-fit.
However, he hopes to play at least part of a game in Sweden.
New signing Graeme Le Saux will fly out to join his new team-mates later in the week, but not until after tomorrow's opening friendly against Jonkoping.
Antti Niemi (knee) and new signing Darren Kenton (calf) are the only players to miss out through injury.
