South Africa bowling coach Allan Donald has left the United Arab Emirates and returned home due to family reasons.
The second and final Test between South Africa and Pakistan gets underway in Dubai on 23rd October, with the Proteas having to win to claim a share of the two-match series.
Joining the squad in the UAE in Donald's absence will be Cricket South Africa (CSA) High Performance Coach Vincent Barnes.
Barnes was due to fly out to the UAE ahead of the One-Day International series but will now head out earlier than planned.
"One of the key characteristics of our environment has been our commitment to making sure our players and management are in a good space both on and off the field," Team Manager Dr. Mohammed Moosajee said.
"Vinnie (Barnes) has worked closely with Russell (Domingo) and Gary (Kirsten) in the past and will no doubt fit in comfortably into the environment. We wish Allan all the best during this difficult time," he added.
Coach Domingo added: "Vinnie is probably one of the most experienced bowling coaches in South Africa and will bring a lot of knowledge and skill to the environment. He has worked with all of the bowlers at either national or High Performance level so he is not coming into the setup cold.
"It will also be important to keep the information flowing between himself and Allan but I am confident of the expertise he brings."
Meanwhile, Hashim Amla remains in South Africa with his wife who is due to give birth to the couple's second child.
He returned home after the first Test with the intention of joining back up with the squad but as the baby has not yet arrived, his participation in the second Test is now in doubt.
