An injury to captain Faf du Plessis took some of the gloss off a 200-run win for South Africa in the third and final ODI against Bangladesh at Buffalo Park here. Du Plessis retired hurt on 91 and had to be helped off the field with an acute lower back strain and took no further part in the match. He was withdrawn from the two-match T20Is up next.
