LONDON:-Graeme Smith has taken a step closer to full retirement with confirmation he will not complete his three-year deal with Surrey in 2015 after receiving medical advice following knee surgery. Smith was forced to curtail his 2014 campaign in May after being diagnosed with fractured right knee which required an operation. It was the second time in two seasons that he had withdrawn through injury - in 2013, the first year of his much-vaunted Surrey deal, it was an ankle problem which cut short the summer.–Agencies
