Australia captain Aaron Finch said on Thursday he could pull out of his team's pivotal final Super 12 match at the Twenty20 World Cup against Afghanistan today (Friday) because of a hamstring injury.
Finch hit form on Monday with a 44-ball 63 in the win against Ireland but was unable to field after feeling a "twinge" during Ireland's innings. The defending champions will probably have to beat Afghanistan by a big margin in Adelaide to have any chance of making the semi-finals as one of the two top teams in Group 1.
"I will test out properly this afternoon to make sure that I am not hindering the side at all leading into the game," said Finch.
"Because that's the worst possible scenario that you leave the guys short out there with one player fewer."
David hurt his hamstring while batting and did not take field in Ireland's chase.
"He is in exactly the same boat. We will know more during training," said Finch.
Wicketkeeper Matthew Wade will lead Australia if Finch has to sit out.
Afghanistan, who are out of the final-four race after two of their matches were washed out, have injury concerns over leading spinner Rashid Khan.
