Vernon Philander has been ruled out of the Test series against England due to an ankle injury sustained in India and Dale Steyn is rated 50-50 for the third Test in Johannesburg, but Kyle Abbott has recovered from a hamstring strain. Steyn suffered a shoulder injury in Durban, which ruled him out of the Test at Newlands and will now see another specialist for a second opinion ahead of a fitness test when the squad meets again in Johannesburg on Monday.On Tuesday Steyn was in good spirits over his fitness when he tweeted: "Start bowling again today. #lekker."But it would be no surprise if South Africa was cautious after his recent injury history.Steyn has been injured nine times in the past two-and-a-half years, has sat out four of their last six Tests, and his problems seem to stem from each other. He missed three of the four matches in India after suffering a groin strain in the first Test that ultimately resulted in seven weeks on the sidelines.That lengthy period off the field contributed to the shoulder problem, caused by heavy bowling loads in the Durban Test after a rest."Vernon Philander is a no-go for the Test series. He is still very much in his rehab phase," said Mohammad Moosajee, the South Africa team manager."Kyle Abbott has made a full recovery from his hamstring strain and he will be ready for the Johannesburg Test."Dale Steyn is pretty much 50-50. He has another appointment with a shoulder specialist in Cape Town today and will be reassessed in Johannesburg on Monday."The full squad for the final two Tests will be named tomorrow. ..
