Eoin Morgan had to miss England’s second one-day international against Australia after a back spasm, handing the captaincy to Jos Buttler.
Morgan, whose team are 1-0 up in the five-match series, felt sudden discomfort on the morning of the match in Cardiff.
In his absence, England brought in Sam Billings as a specialist middle-order batsman – with Buttler retaining the gloves despite his extra leadership responsibilities.
He has previously led his country in three ODIs against Bangladesh in October 2016, with Morgan missing England’s 2-1 series win for security reasons, and four Twenty20 internationals.
England, who were put into bat on a cloudy morning, made just the one enforced change.
There were two for Australia as Jhye Richardson replaced injured strike bowler Billy Stanlake and D’Arcy Short made his ODI debut at the top of the order – with seamer Michael Neser dropped to accommodate the extra batsman.
