Cremer, 39, had not played for Zimbabwe in seven years when he made his comeback to play in the T20 World Cup, before a left-arm injury sidelined him from selection after the tournament.
Zimbabwe will also be monitoring Ngarava’s recovery. If fit, he is expected to lead Zimbabwe for their ODI series against Australia in September.
For now, they take on Namibia and South Africa in a double round-robin format, which commences on August 28 and will take place in Windhoek. The top two sides advance to the final on September 6.
