Dean Moodley (Sharks, SA Schools) and Ofentse Moeng (Blue Bulls, SA Schools A) have been named as respective Team managers, SA Rugby Confirmed on Tuesday.
The SA Schools and SA Schools A teams will be announced a week after the conclusion of the Under-18 Craven Week, which will be hosted at Grey College in Bloemfontein from Monday, 1 July to Saturday, 6 July.
Matches will be played on Friday, 9 August, Tuesday, 13 August and Saturday, 17 August at school venues across the Western Cape.
SA Rugby CEO, Jurie Roux, congratulated Nkosi and Nomlomo.
"These teams are important in our youth rugby landscape. The SA Schools sides are an important development step in the careers of many of our top schoolboy players, which means Mzwakhe and Phiwe will have a big job to deliver well-balanced teams as these boys prepare for the next step in their careers."
