Chris Rogers is still dealing with the effects of concussion and is no certain starter for the second Test against the West Indies in Jamaica starting on Thursday.
Rogers was ruled out of the first Test in Dominica after he was struck on the helmet by a net bowler three days before the match.

The decision to withdraw him from the Test was in line with Cricket Australia's new approach to concussion and team doctor Peter Brukner said at the time Rogers would return to training once his symptoms had subsided, which he expected would be "in a few days".

But five days after being ruled out, and a day after Australia had wrapped up the opening Test inside three days, the 37-year-old is still feeling the effects of the blow.
"Chris is still experiencing some symptoms of concussion and the plan is have him take it easy another few days," Dr Brukner said.
"In regards to his availability for selection for the second Test it's too early to say at this stage."

Rogers was replaced at the top of the order for the first Test by Shaun Marsh, who made a brilliant century in Australia's tour match in Antigua 10 days ago.
Marsh's move to opener meant Adam Voges slipped into the vacant No.5 position and capitalised on his chance by making a match-winning century on the second day.

Voges's performance would seemingly leave Marsh vulnerable should Rogers be fit to return to the side and resume his partnership with David Warner.
But five days out from the second Test, Rogers is yet to be guaranteed a return for what would be one of his final acts on the international stage before he retires from Test cricket following the upcoming Ashes series.

Captain Michael Clarke said on Friday selectors would wait for further information from Brukner and the medical staff before making a final decision on the side for the Kingston Test.
"I haven't had a chance to speak to Bucky or the doctor to see where he's at now," Clarke said after Australia's nine-wicket victory in Roseau.
"I think he had some throw-downs in the nets today, he did some running around the ground the last couple of days, so from all reports he's heading in the right direction.
"But that'll be determined by the Doc and Chris will back his judgment, as we will."
Australia's victory in Dominica meant they have retained the Frank Worrell Trophy with the second of two Tests still to come, starting on Thursday.
