Chris Rogers has undergone further precautionary tests on the head injury he suffered when hit on the head by a bouncer from England bowler James Anderson.
The Australia batsman was struck on the helmet during the first innings of the second Ashes Test at Lord's.
Rogers, 37, didn't appear to fully feel the effects until the second innings, when he was forced to retire on 49.
He underwent scans to rule out serious injury last week, but had further checks on Wednesday morning to discover the root of the problem.
David Warner, who was batting with Rogers at the time, revealed how the injury led his fellow opener to believe the Lord's grandstand was moving.

"That was bizarre," Warner told Australia's Daily Telegraph.
"I came down the wicket and I had to look twice, because I didn't really know what was going on.
"He actually said to me 'the grandstand is moving' and I said 'No, it's not'.

"I was worried and so was he. I had no idea what was going on.
"He said: 'I don't know what's happening here'. So I said: 'Just sit down'."
Concern for the safety of cricketers has been elevated since the tragic death of Australia's Phillip Hughes.
Hughes died on 27 November last year, two days after being hit below the ear by a bouncer during a Sheffield Shield match.
