Australia's Usman Khawaja has been sent for scans on his jaw after being struck on the helmet by a bouncer during a Cricket World Cup warm-up against West Indies.
The top-order batsman had just five runs to his name when he was forced to retire hurt.
Khawaja was struck by a delivery from Andre Russell during the second over of Australia's run chase in Southampton.
He is not expected to play any further part in the match.
Australia begin their World Cup campaign against Afghanistan on June 1 at Bristol.
They have further warm-ups with hosts England and Sri Lanka prior to beginning the defence of the title they won when co-hosting in 2015.
