Basseterre - Australia opener David Warner is set to miss the remainder of the one-day series in the West Indies after breaking a finger during Saturday's 36-run win over South Africa, the tourists said Sunday.
Warner was man of the match for his 109 from 120 balls, his sixth one-day international hundred, which moved Australia to the top of the three-team table.
But he took a blow to his left index finger while fielding and an X-ray on Sunday revealed a fracture.
"We will assess the situation over the coming days to see if the injury requires a surgical option but should that not be the case then David is likely to be available to return to play in somewhere between two and six weeks," said Australia team doctor Geoffrey Verrall.
A decision on Warner's further participation in the competition will be made in the next few days, said a Cricket Australia spokesman.
However, with the tournament ending on June 29, it seems likely that the 29-year-old's tour is over.
"It's obviously disappointing to be sidelined given the form I've been in and given the important stage the tri-series is at, but it's always important to look at the positives," said Warner.
"This downtime, however long or short it is, will give me the chance to freshen up and spend quality time with my family after an intense period of action, with a home summer that was followed by trips to New Zealand and South Africa, plus the World Twenty20 and the Indian Premier League."
