London: Pace bowler Jake Ball added to England's injury problems before the first Ashes Test against Australia when he sprained an ankle in a warm-up game.
Bowling his fourth over on the second day against a Cricket Australia XI, Ball collapsed in his delivery stride and limped off the field in Adelaide.
England said the 26-year-old would be assessed overnight.
Leg-spinner Mason Crane took 3-78 as the hosts made 233-9 declared, before England reached 5-0, a lead of 65.
Fielding coach Paul Collingwood, 41, came on as a substitute fielder for Ball for one over.
James Anderson claimed 2-30 and Chris Woakes 2-48 at the Adelaide Oval, while former Australia wicketkeeper Tim Paine made 52 and Simon Milenko 50.
On Tuesday, England fast bowler Steven Finn left the tour with a knee injury and was replaced by the uncapped Tom Curran.
All-rounder Moeen Ali is missing the four-day floodlit match because of a side injury.
It is the second of England's three tour games before the opening Test in Brisbane starts on 23 November.
