Giant lock Eben Etzebeth is set to play his first competitive match in 10 months when he starts for South Africa in their Rugby Championship opener against Argentina at King's Park on Saturday.
Springboks coach Rassie Erasmus has confirmed that last year's captain had been given the medical all-clear, and is likely to play the first hour against the Pumas having only just returned from a shoulder injury followed by a back problem.
"His match fitness is a concern and it's for that reason that we won't see him playing much more than 60 minutes this week," Erasmus told reporters on Monday.
"We just received the clearance from the specialist. He's been training full on with us ever since the end of the Stormers' Super Rugby campaign, but we've been waiting on this (medical clearance)."
Etzebeth, 26, brings an enormous physical presence to the pack and is a solid line-out option with 67 caps to his name since his debut 2012.
His return along with the likes of loose-forward Warren Whiteley and hooker Malcolm Marx had added significant strength in depth for Erasmus from the side that beat England 2-1 at home in June.
Erasmus is well aware that after success against England, expectations are the Boks will brush aside an Argentina team who have won just two of their last 18 tests - against Italy and Georgia.
But the coach expects a much improved South American outfit after a solid Super Rugby campaign for the Jaguares, who make up most of the Pumas side.
"The Jaguares won all their matches (on tour) in Australasia and beat all of the South African teams.
Argentina now have the same coach in Mario Ledesma and the players will have a good idea of what's expected of them," Erasmus said.
Australia will host South Africa in the third round of the series in Brisbane on September 8.
