Cape Town - Two-time Indian Premier League (IPL) champions, the Kolkata Knight Riders, have parted ways with former Proteas great head coach Jacques Kallis and assistant coach Simon Katish.
According the Cricinfo's website, Kallis' departure ends a nine-year relationship - as player and then coach - with the franchise.
Kallis was appointed Knight Riders' head coach in October 2015, taking over from Trevor Bayliss, the current England coach.
In this year's IPL, the side finished fifth, losing out on playoff qualification based on net run-rate, after a six-match losing streak midway through the season.
Kallis, however, could remain a part of the Knight Riders brand, according to team CEO Venky Mysore.
"Jacques Kallis has been an integral part of the KKR family and will always remain so," Mysore said, while announcing the changes.
"We will be exploring ways of working with Jacques as we pursue our vision of establishing the Knight Riders brand as a global brand."
Kallis, too, released a statement following the decision.
"After nine fantastic years with KKR since 2011, as a player, mentor and head coach, it's time to explore new opportunities," he said.
"I would to like to thank the owners, management and fellow players for many happy memories."
Kallis, 43, played 166 Tests, 328 ODIs and 25 T20s for South Africa and is widely acknowledged as one of cricket's greatest ever players.
