Australian paceman Brad Williams will miss the two remaining one-day matches in Zimbabwe because of a back injury.
Williams suffered back pain while bowling in Harare
Williams had to leave the field after bowling only five overs in Tuesday's seven-wicket win in Harare.
"Brad is experiencing significant pain in his lower back and there simply isn't enough time remaining on this tour to investigate the problem fully.
"With his history of back problems, we felt he should go back to Australia," said team physio Alex Kontouri.
"He was treated for back pain earlier in the tour but after rest and treatment the condition improved. That the pain has flared up again is a concern."
Williams, who has played four Tests and 24 one-day internationals, will undergo a scan following his return home.
He will not be replaced and Australia will pick from their 13 remaining players for the final two games on Thursday and Saturday.
"About third or fourth ball I felt something go in my back. It was like somebody jabbed me with a
needle," said Williams.
"I was struggling for breath. The pain was radiating up.
During my last over I was really gritting my teeth."
"It would be very unusual at my age to have stress
fractures. It's more likely to be a facet joint. If that's the
case I'll get a couple of injections and should be right in a
couple of weeks."
