Australia will be without opening batsman David Warner for at least the first two one-day internationals against West Indies after fracturing a thumb during nets.
The explosive left-hander was struck by a Mitchell Johnson delivery while practising at Perth, the venue of the first two of four ODIs to be contested with West Indies in February.
The injury to Warner has meant a call-up for Usman Khawaja, who will join the team at the WACA before the first match of the series on Friday.
"While the fracture is very minor, it is not worth taking any risks," physiotherapist Kevin Sims said.
"The injury will keep him out of at least the next two matches against West Indies. We'll assess how he is progressing after that to determine his availability for the remainder of the series."
West Indies warmed up for the series with a 23-run defeat to a Prime Minister's XI in a high-scoring encounter in Canberra on Tuesday night.
