Australia will be without all-rounder Moises Henriques for the opening ODI against the West Indies on 1 February, after he underwent surgery on an injured finger on Saturday.
The player was struck on his index finger twice in the space of a few days, first while training with the national side in the ODI series against Sri Lanka, and then while playing for New South Wales.
NSW team physiotherapist Murray Ryan said: "Moises was struck on the index finger of his right hand batting yesterday, aggravating the same finger injury sustained during recent Australian ODI training.
"Due to concern over increasing swelling and infection Moises was reviewed by a Sydney hand specialist this afternoon and has undergone a minor surgical procedure.
"Moises will be unable to play or train for at least one week. His availability for state and international cricket will be determined as the injury heals."
The Aussies and the Windies will play five ODIs and one T20 in the space of two weeks, and the first two games will be played at the WACA in Perth.
