Australia have lost another player to a hamstring injury for Friday's one-day international against England in Hobart.
Shane Watson will not play in Australia's one-day international against England on Friday, although stand-in captain Steven Smith insisted the all-rounder will be fine for the ICC World Cup.
With regular skipper Michael Clarke still recovering from hamstring surgery and David Warner rested with soreness in the same muscle, Watson sent a familiar scare through the Australian camp on Thursday when he complained of tightness at training.
The 33-year-old has a history of hamstring problems and Smith explained Australia did not want to take a risk.
"The selectors have got to come down and weigh up our options with 'Watto' going to be ruled out tomorrow," Smith said at a media conference.
"[Chairman of selectors] Rod [Marsh] is on his way down here, so we're not 100 per cent sure of the eleven yet.
"He [Watson] bowled this morning, I think he's just a little bit tight.
"I don't think it's anything too major. It's more of a precautionary measure to make sure he's right for the World Cup."
Watson could be replaced by Mitchell Marsh, who has only just recovered from a hamstring injury. The all-rounder was slated to play in a grade cricket match in Sydney on Saturday, however.
Australia have already been forced into two changes for the ODI in Tasmania, with deputy captain George Bailey suspended for slow over-rates and Warner rested.
Smith revealed that Shaun Marsh will open the batting in Warner's absence, while Cameron White will replace Bailey in the middle order.
"Shaun Marsh is going to bat up the top with Aaron Finch," Smith added.
Australia have won their opening two ODI's in the tri-series against India and England.
The English bounced back from their first-up loss to defeat India by nine wickets on Tuesday.
