Cricket South Africa CEO Haroon Lorgat made the announcement on Wednesday in Johannesburg, shortly after the launch of the Jo’Burg Giants T20 Global League franchise.
Gibson is currently the England bowling coach, but will leave the role upon the conclusion of the current Test series against the West Indies. The 48-year-old was a fast bowler during his playing days, and has two tests under his belt, while he also enjoyed stints in South Africa, representing the likes of Border and Griqualand West.
He has previously been head coach of the West Indies, during which time he guided them to success in the T20 World Cup in Bangladesh in 2012.
Gibson is the second foreign coach to take over the reins of South Africa, following in the footsteps of the late Englishman Bob Woolmer, who had the job from 1996-1999.
The West Indian replaces Russell Domingo, who has been appointed head coach of the South African A side, thus ending his four year tenure as coach of the Proteas. Domingo however will first focus on the T20 Global League, where he is coach of the Pretoria Mavericks franchise.
After revealing the news, Lorgat said: “On behalf of the board, I would like to thank Russell Domingo for his positive contributions during his time with the Proteas and I am delighted he will remain in our setup as head coach of the South Africa A side.”
“This is an important position that prepares our up-and-coming players in the next stage of their journey to become potential Proteas. I must also thank the England Cricket Board for their understanding and co-operation in releasing Ottis from his current contract.”
