Diabate's French club Bordeaux announced on Thursday that the 26-year-old agreed to undergo surgery after a consultation with a specialist in Marseille last month, accepting that it was "essential for the successful continuation of his career".
Bordeaux's leading scorer this season with eight league goals, Diabate, who stands at an imposing 1.94m, had been called up by Mali for the Cup of Nations, which will be held in Equatorial Guinea from 17 January to 8 February.
