Ricky Ponting is set to make an announcement on his international future after being dropped from Australia's one-day side.
The out-of-form batsman has not been selected for the next two matches against Sri Lanka and India.
Ponting, 37, who captained Australia to two World Cup wins, has scored only 18 runs in five innings in the tri-series.
He is now "considering his future" and will hold a news conference in Sydney at 0000 GMT.
"Ricky has been dropped due to his lack of form in this series," confirmed national selector John Inverarity.
"He will consider his future over the next couple of days. We hope he remains available for Test match cricket but there can be no guarantees.
"He will talk it over with his family and with his manager.
"He's wondering whether he retires completely from ODI cricket ... and then there are the implications for Test cricket."

Highest-scoring one-day batsmen of all time

1. Sachin Tendulkar (Ind) Runs: 18,179. Average: 44.88
2. Ricky Ponting (Aus). Runs: 13,704. Average: 42.03
3. Sanath Jayasuriya (SL). Runs: 13,430. Average: 32.36
4. Inzamam-ul-Haq (Pak) Runs: 11,739. Average: 39.52
5. Jacques Kallis (SA). Runs: 11,481. Average: 45.55
The Tasmanian's omission from the squad comes after he stepped in to lead the side to one victory and one defeat in their previous two games in the absence of injured skipper Michael Clarke.
"Ricky being prepared to take over the captaincy in Clarke's recent absence for the sake of the team is yet another example of his selfless attitude and team-first focus," Inverarity added.
Ponting, who resigned the captaincy after the 2011 World Cup, has played in 375 one-day internationals, scoring 13,704 runs at an average of 42.
The Tasmanian has hit 30 centuries and 82 half-centuries as well as taking 160 catches.
"Ricky's record speaks for itself. He is one of the truly great performers in the history of Australian ODI cricket, with his reputation enhanced further by him captaining Australia to two World Cup victories," said Inverarity.
"Ricky's contribution goes far beyond his batting statistics and his brilliant fielding. The example he sets in every respect and his extraordinarily positive influence in the dressing room is acknowledged by all.
"He is held in the highest possible regard by his team-mates and there is no higher accolade than this."
Ponting is now expected to weigh up whether to retire from international cricket or continue as a Test player.
Facing calls to quit at the end of last year following a run of low Test scores, he silenced his critics by smashing 544 runs at an average of 108.8  in the recent 4-0 whitewash of India.
Clarke returns to the 13-man squad after recovering from a hamstring injury, while Shane Watson is also back from injury and pace bowler Ryan Harris replaces Mitchell Starc.
Inverarity also confirmed that 24-year-old Matthew Wade was the side's preferred wicketkeeper and he would be touring the West Indies alongside out-of-form Test gloveman Brad Haddin.
