Springbok coach Rassie Erasmus has named a strong squad of 39 players and an additional 14 players on a standby list for the Castle Lager Incoming Series.
It kicks off with a challenging two Tests against Ireland on Saturday, 6 July, followed by a one-off Test against Portugal.
SA Rugby says the two uncapped players named in the squad were Vodacom Bulls hooker Johan Grobbelaar and front rower Jan-Hendrik Wessels, while Cheslin Kolbe (wing) and Lukhanyo Am (centre) are back from injury.
Handre Pollard (flyhalf) and Jasper Wiese, are back in the squad, with Wiese only be available for selection once he completes his suspension from a dangerous tackle.
Erasmus also called up Rugby World Cup winners Siya Kolisi, and RG Snyman (lock), who both joined the squad in London following their club commitments.
Three players who made their Test debuts against Wales at Twickenham on Saturday, which the team won 41-13 – Edwill van der Merwe (wing), Ben-Jason Dixon (utility forward) and Sacha Feinberg-Mngomezulu (utility back) – were included in the group.
The 39-man squad features 22 forwards and 17 backline players, with Erasmus set to name the captain for the competition closer to the Ireland Test.
