Broos decided against selecting the in-form Mamelodi Sundowns duo while instead prioritising youth for his squad selections so far.
Bafana Bafana has been drawn against Morocco, Zimbabwe and Liberia in the Group K for the 2023 Afcon qualifiers with Radebe calling for the addition of experience.
"For me, it's better when we have that support in terms of senior players in the team where you have a lot of young players because you need players with character," Radebe said.
"You need players that will raise their hand, players that will go and put their body on the line which I think Andile Jali and Zwane can come in and help.
"But it's not up to me, that's just my opinion, and it is the coach's decision at the end of the day.
"I think we have to wait and see, but I believe in most of the teams we see for the Afcon draw most of the players come from overseas, and it's going to be tough.
"I think they have seen when we played France, it was hard, but we can take the positives because we played against one of the best teams in Europe."
