In the wake of Patrick Lambie's injury on Saturday, experienced fly-half Morné Steyn has been called into the Springbok squad.
SARU confirmed that the 60 cap veteran will join the squad and will provide cover for Elton Jantjies, who will more than likely start for South Africa this Saturday for their second game of the three-Test series with Ireland.
This comes after Lambie was concussed during their 26-20 loss to Ireland in Cape Town.
Coetzee explained that Steyn was always the next in line to join the team in case of injury to one of his fly-halves.
"I made it clear we would definitely consider Morne as a replacement option because of his vast experience, and I would therefore not hesitate to draft him into the match-day squad," said Coetzee.
"Garth April is still a talented young man and was selected to learn and to develop. It is his first year in Super Rugby and his involvement with the squad will benefit him in the long run. Pat will return home for this week and we want to wish him well with his recovery.
Coetzee confirmed the full squad will remain in camp for the entire week. Last week, the Springboks released four squad members to the SA ‘A’ team for their clash against the England Saxons in Bloemfontein.
Coetzee explains the decision: "All our players will stay with us for this week as SA ‘A’ coach Johan Ackermann has requested to give playing opportunities to more members of his squad. Our players will be on standby should they be needed on short notice."
