Uncapped paceman Dane Paterson has been called up to the South Africa squad for the second Test against Bangladesh after Morne Morkel was ruled out for up to six weeks.
Morkel suffered a side strain on day four of the Proteas' crushing win 333-run victory over the Tigers at Senwes Park and scans revealed that he sustained a grade two tear to his left abdominal oblique muscle.
The quick, who took two wickets in the first over of Bangladesh's second innings in Potchefstroom on Sunday, will be out of action for at least four weeks, so he also misses three one-day internationals and two Twenty20s.
Proteas team manager Dr Mohammed Moosajee said: "Morne complained of a sharp pain to his left side yesterday and immediately aborted his bowling spell.
"Subsequent scans this morning confirmed a grade two tear to the left abdominal oblique muscle which rules him out of the remainder of the series. He will need a 4-6 week recovery period and will target a return for the T20 Global League in November."
With Vernon Philander, Chris Morris and Dale Steyn also sidelined, Paterson could make his Test bow when the second Test gets under way in Bloemfontein on Friday.
Keshav Maharaj (4-25) and Kasigo Rabada (3-33) starred in Morkel's absence on the final day of the opening Test as the tourists were skittled out for only 90.
