T20 World Cup: Injuries to Finch, David and Stoinis concern Australia ahead of crucial match against Afghanistan

Finch underwent a fitness Test here on Wednesday, doing a series of run-throughs and stretches of his hamstring, watched by team fitness staff and selection chair George Bailey.

Finch's injury was of the most concern for Australia given the 35-year-old's history of hamstring injuries.

"Little hammy twinge I think," Finch said after the win on Monday.

"I'll get a scan tomorrow (Tuesday). Unfortunately, I've had a history with them so we'll see how it goes. It doesn't feel too bad at the moment but generally, overnight they can stiffen up.

"We'll get a scan and get the full results, but I am very hopeful (of playing against Afghanistan) but we'll know more (Tuesday)." If Finch is ruled out of the game, wicketkeeper Matthew Wade will captain Australia against Afghanistan. Wade had carried out captaincy duties after Finch came off the field against Ireland.

Young all-rounder Cameron Green could replace Finch as the opener if the captain is ruled out.

Green, who was a late inclusion to the squad in place of an injured Josh Inglis, had centre wicket practice at Karen Rolton Oval, hitting a series of massive sixes in the background.

Australia need to beat Afghanistan on Friday to have a shot at qualifying for the semifinals.

The all-important Net Run Rate (NRR), which could decide whether they qualify for the semifinals, lifted to -0.304 after the win against Ireland but is still below England (0.239) and New Zealand (2.233).

All three teams are currently on five points after four matches.
