Kingston (Jamaica) June 10 (IANS): Australia opener Chris Rogers has not fully recovered from concussion and has been ruled out of the second Test against the West Indies, starting here on Thursday.

Rogers was struck on the helmet during training in Dominica nine days ago and he experienced dizzy spells and a headache later that evening. Shaun Marsh is set to replace Rogers at the top of the order for the match at Sabina Park, as he did in the first Test.

Rogers was ruled out of the first Test by team doctor Peter Brukner, a decision made in line with Cricket Australia's policy on concussion, cricket.com.au reported on Wednesday.

Rogers' symptoms were expected to subside in a few days and it was likely he would recover in time for the second Test. But Brukner said Rogers was still experiencing symptoms and it was decided on Wednesday that the opener would again miss out.

"Chris has improved but he is still not 100 per cent so we are restricting his training (and) therefore he is unavailable for selection for the second Test," Brukner said.

"While most concussions resolve within a week there is a significant number who remain symptomatic and require a longer period of recovery. Unfortunately Chris is in this category. We will continue to monitor his progress and hopefully it will not be too long before he is back to full training," he added.
