Dale Steyn is unlikely to be risked for the final one-day international against England at Durban to ensure he recovers from a hamstring strain in time for the Test series which starts on December 16.

Steyn missed the fourth ODI in Port Elizabeth after suffering the injury at Newlands when he managed just six overs in South Africa's 112-run victory before leaving the field. Even though the home side trail 2-1, and can only earn a share of the series, they will resist the urge to rush Steyn back into action knowing the major challenge of the Test matches is around the corner.

"For us the priority is the Test series and we would never compromise Dale's chances of being 100% fit for the first Test [at Centurion] by playing him on Friday," South Africa coach Mickey Arthur told reporters in Durban. "Dale had an MRI scan yesterday which showed no major damage. It is only a grade one strain, which is minor, and we will monitor him."

Arthur's cautious approach to Steyn's fitness is understandable given that Jacques Kallis is only rated 50-50 for the opening Test as he recovers from a fractured rib that has ruled him out of the one-day series. However, Arthur said he was confident that Kallis would be back to full fitness in time for the Boxing Day Test in Durban and even if Kallis can't bowl South Africa could play him as a specialist batsman at Centurion Park.

Without Kallis in the one-day side South Africa have looked unbalanced with Mark Boucher and Ryan McLaren both a place too high in the batting order and they were exposed when the top-order failed at Port Elizabeth.

Following their seven-wicket defeat on Sunday, South Africa joined up again a day earlier than planned in Durban but were prevented from having a proper training session as heavy rain fell.
