Bangladesh captain Najmul Hossain Shanto said his men were focused on the challenge of South Africa rather than their missing all-rounder Shakib al Hasan ahead of Monday's first Test in Mirpur.
The two-Test series is the first international cricket fixture in Bangladesh since a student-led revolution toppled autocratic premier Sheikh Hasina in August.
The series carries points towards the World Test Championship (WTC), with the final in England next year. South Africa currently are sixth in the standings with Bangladesh seventh.
Bangladesh called up uncapped left-arm spinner Hasan Murad to replace retiring Shakib after security fears led the former captain to cancel plans to return home.
