Australia captain Michael Clarke is set to miss the next ICC Champions Trophy fixture against New Zealand tomorrow (12th June).
Clarke missed the opening 48-run defeat to England due to a long-standing lower back injury.
The 32-year-old's continuing injury problems will cast further doubts over his availability for the remainder of the tournament. Doubts will also be cast on his fitness looking ahead to this summer's Ashes which begin on 10th July at Trent Bridge.
Cricket Australia Physiotherapist Alex Kountouris said: "Michael is continuing to have intensive treatment in London, and whilst he is making good progress, he has not improved sufficiently enough to play the game against New Zealand on Wednesday.
"We will continue to monitor his progress and determine his availability for next week's final group game against Sri Lanka."
