Graeme Smith has withdrawn his interest in becoming Cricket South Africa's (CSA) first full-time director of cricket due to concerns over the existing structure.

It was reported last week that former Proteas captain Smith, who played 117 Tests, 197 ODIs and 33 Twenty20 internationals for his country, had interviewed for the position.

According to ESPNcricinfo, the 38-year-old faced competition for the role, which was created after the 2019 Cricket World Cup, from interim post-holder Corrie van Zyl and former national selector Hussein Manack.

However, Smith has pulled out of the running because he does not have confidence the role offers sufficient ability to implement change at CSA.

"Following the news in the media this week that I interviewed for the CSA director of cricket role, I feel it necessary to confirm that I have unfortunately withdrawn my interest for the role," Smith wrote in a statement posted on Twitter.

"I would love to have taken on the role. However, despite my obvious desire to make a difference, during the long and, at times, frustrating process over the last 10 or so weeks of discussions, I have not developed the necessary confidence that I would be given the level of freedom and support to initiate the required changes.

"My passion for our nation's cricketing fortunes remains steadfast and I give my heartfelt best wishes to whomever does take the role on.

"I will continue to support the teams and give my advice and guidance whenever I can."
