South Africa have welcomed the arrival of Francois Steyn to the touring party ahead of their next match against Wales on Saturday.
Utility back Steyn, 23, arrived from club side Racing Metro Paris in time to take part in Monday's training session and may be set to make an instant return to the Test line-up for the match at Cardiff's Millennium Stadium.
Springboks assistant coach Dick Muir has greeted the arrival of Steyn with much relief, particularly in light of South Africa's mounting injury list.
"We miss him when he is not with us," said Muir.
"He covers a number of positions and gives us lots of options in selection, especially with so many centres currently unavailable through injury."
"He can play 10, 12 or 15 and like Jean de Villiers is pretty flexible. I could see them playing together in the centres but we'll have to weigh up all our options in selection."
There was finally some good news on the injury front for South Africa, with Jean de Villiers expected to return to training after being cleared of a suspected muscle tear in Saturday's 23-21 win over Ireland in Dublin.
"It is an acute muscle strain - not a tear - and it's just a bit sore," Roberts said.
"We have to be clever in how we manage him and he should be fine to train tomorrow [Tuesday]."
Loose forward William Alberts continues his recovery from a calf problem sustained in the Currie Cup Final in October and may also be set to challenge for a place in the starting line-up.
"It is a minor calf strain and he did some running today and I am really pleased with him," Roberts said.
"We'll continue to monitor him in the hope that he will be fit to play on Saturday if selected."
