Australian opener David Warner will have scans on an injured thumb after being forced from the field early in the second one-day clash of their series with England at Lord's.
On the second ball of the day on Saturday, and Warner's first, the left-handed opener was struck on the left thumb from a nasty rearing delivery by England paceman Steve Finn.
Warner attempted to fend the ball away but only managed to glove it over the head of wicketkeeper Jos Buttler.
He scampered through for a single before calling team doctor John Orchard to the field.
After a short consultation with Orchard and medical staff, the vice-captain retired hurt.
He will not field during England's innings, but has been made available to bat later in Australia's innings if required.
"He's been assessed by the team's medical staff, has received a painkiller and will bat when required," said a Cricket Australia spokesperson.
"He will have an X-Ray when he's finished batting and won't field."
It throws into question whether he will be available for the remainder of the five-match ODI series.
The worst case scenario, a broken thumb, would also throw into doubt Warner's prospects of being fit for October's two-Test series in Bangladesh.
The 27-year-old's availability for that series will be crucial, with Australia already required to find replacements for recently retired batsmen Chris Rogers and Michael Clarke.
After Bangladesh, Australia have a busy summer which includes home Test series against the West Indies and New Zealand.
