Matfield, who is the most capped Springbok, has been tasked to lead a panel of experts in selecting the Hero of the Day recipients at the Craven Week, which will take place at St Stithians College in Johannesburg from July 17-22.
"Being chosen to be part of the Craven Week really takes me back to when I played in the tournament back in 1994 and 1995," Matfield said.
"For me, Craven Week was a stepping stone in my rugby career and I want to thank SARU for organising tournaments like these to identify talent from a young age.
"I look forward to playing a part in the tournament and bringing some of my experience and expertise to what I believe will be an action-packed week," he added.
Matfield, alongside appointed panel of rugby specialists, will on each day of the U18 Craven Week be tasked with identifying and recognising a standout player that embodies the qualities of a hero, the Hero of the Day.
The Hero of the Day is not necessarily the best player on the field. He is the flank that made three successive tackles and forced the turnover; the scrumhalf that took a quick tap and dived over for the match-winning try; or the centre that made a courageous try-saving tackle.
