By Ian RansomMelbourne — Pace spearhead Kagiso Rabada has been ruled out of the ODI series against Australia and is a doubt for the following Test series against Pat Cummins’ team as he battles a hamstring injury.Cricket South Africa said Rabada had suffered a right hamstring strain and would miss the three ODIs starting on September 24 in Durban.“His availability for the three-match Test series against Australia will depend on how he progresses through his rehabilitation, with a decision on his selection to be made closer to the series,” CSA said in a statement.Rabada’s domestic bowling coach Allan Donald told South African media Rabada’s hamstring injury could see him sidelined for up to 10 weeks.The first Test starts on October 9 in Durban, with Gqeberha and Cape Town also hosting matches.Losing Rabada for the Test series would be a huge blow for South Africa, who beat Australia in the World Test Championship final at Lord’s last year when the 31-year-old took nine wickets.Rabada has an average of 21.39 in 11 Tests against Australia, slightly better than his exceptional career average of 22.03.
