Graeme Smith says he has yet to accept an offer to work with South Africa as a batting consultant on a formal basis.
Former Proteas skipper Smith, who retired from international cricket in 2014, helped out at a training session on Friday ahead of the second Test with England in Cape Town as the hosts look to bounce back from their 241-run defeat in Durban.
It was subsequently announced that the 34-year-old had been brought on board to assist a struggling South Africa batting line-up for the remainder of the four-Test series.
However, Smith revealed on Saturday that he is still considering whether he can take up the position, given his existing broadcasting commitments.
Speaking in his role as a summariser on BBC's Test Match Special, Smith explained: "In Durban, I was asked to come down and just join the guys for the training session on New Year's Day, just to come and spend some time with the guys and chat to them, hopefully help them.
"Obviously, they're low on confidence, maybe you can say something or work with them on a certain aspect.
"But when I got here yesterday [Friday] they sort of offered me an extended role and the fact that it's been announced in that way is probably not right because I was just asked yesterday. The role was offered for me to consider and that's really as much as it is at the moment, I would say.
"I've got commitments that I've already made. It's something that I need to think about.
"I definitely haven't committed to the role yet. I'm more than happy to help the guys whenever possible, obviously South African cricket is always close to my heart, but I need to consider if it's the right thing for me and I certainly have commitments that I have already engaged in."
Smith, who captained South Africa in 109 of his 117 Tests, recently hinted at a shock return to international cricket as a player.
