Duo join Springbok squad

Odwa Ndungane replaces JP Pietersen on the wing after Pietersen returned home with a hamstring injury he suffered in last weekend's 32-25 win over the Wallabies in Perth.

Danie Rossouw (pictured), returning from his own hamstring injury, was added to the bench to replace injured lock Andries Bekker, who was sent home because of a shoulder problem.

"Whilst we have a lot of versatile players in the squad, Odwa in the natural winger and therefore was the first choice," South Africa coach Peter de Villiers said.

"He has been running the moves with us for sometime and is familiar with the defensive patterns so he should fit in pretty easily."

Lock Bakkies Botha, who was replaced by Bekker last weekend, and wing Bryan Habana, who scored two tries in the match, were both selected despite having minor injury concerns.

Habana joined his team-mates at training on Tuesday but Botha sat out the session, prompting de Villiers to call up Johann Muller as cover.

Muller has played 23 Tests for the Springboks but was overlooked for the Tri-Nations after his last appearance in the third and final Test against the British and Irish Lions.

"We are looking forward to Johann joining the squad. He is an experienced campaigner and has served the Springboks well in the past," de Villiers said.

The Springboks are unbeaten after four matches in this year's Tri-Nations and a victory at Lang Park on Saturday will wrap up the title before their final match against New Zealand in Hamilton on September 12.

"We have not won the Tri-Nations title yet and there are still two tough games to play," De Villiers said.

"We are focusing on the immediate task at hand and that is to do well against Australia on Saturday.

"We do not chase records but strive to improve on each and every performance. This team can still get much, much better and is playing winning rugby whilst still making errors.

"It excites me when I think of what these players could still do on the field."
