South Africa have recalled fly-half Meyer Bosman to their Tri-Nations squad after Andre Pretorius failed to recover fully from a thigh injury.
Bosman played against Wales and France last November
Bosman, who played two Tests at
the end of 2005, will be back-up for first choice Jaco van der Westhuyzen.
There are four newcomers in the 28-man squad for the tournament.
Under-21 captain Chiliboy Ralepelle, Bulls wing Akona Ndungane, utility back JP Pietersen and Bulls flanker Pierre Spies all earn their first call-ups.
London Irish hooker Danie Coetzee has also earned a recall for the first time since 2003, although is likely to understudy captain John Smit.
Pretorius hopes to be fit for the Boks' third match against Australia in Sydney on 5 August, after opening games against the Wallabies in Brisbane on 15 July and New Zealand in Wellington on 22 July.
"No-one spoke to me so it was quite a shock when I was included in the squad," he said.
"I should probably play a club game first to see how the groin holds up."
Ndungane is cover for Habana
Wing Bryan Habana was also named in the squad despite a rib injury, with Ndungane poised to step up if Habana is not fit to travel.
"The new guys will all get some game time but we will manage the youngsters very carefully," said convenor of selectors Pieter Jooste.
He also confirmed coach Jake White would be travelling with the team despite rumours linking him with a job in the England set-up.
"Jake White is the Bok coach, nothing has changed and he will travel and coach the team," he said.
