The SA Emerging team, which includes six Springboks in the starting line-up and two more full internationals amongst the replacements, will play the feature match of the day at 19.00 (18.00 SA time; 16.00 GMT).
Coach Peter de Villiers has selected a formidable team, with Springboks Bevin Fortuin (Cheetahs, fullback), Jaco Pretorius (Lions, utility back), Tonderai Chavhanga (Stormers, wing), Kabamba Floors (Cheetahs, loose forward), Solly Tyibilika (Lions, flank) and Eddie Andrews (Stormers, prop) in the starting line-up.
Tyibilika, who almost lost his national and Lions contracts because he repeatedly failed to turn up at practice sessions, and Chavhanga, who has had a run of injuries, have played very little rugby this year.
Former Springbok Sevens captain Promising Jonathan Mokuena has also had very little game time in the 15-man code and will also be keen to make an impression.
Teams competing in the tournament are allowed to have all their players who are not in the run-on team on the bench, but may use only seven substitutes.
The two Boks on the bench are Cheetahs utility back Meyer Bosman and fiery Bulls loose forward Hilton Lobberts.
