Calcutta: Missing the matches against England and New Zealand due to injury, James Faulkner is confident he has lost none of his batting prowess that made him Australia's master finisher as he prepares for a likely return against Afghanistan in Perth on Wednesday.

According to the Sydney Morning Herald, Faulkner underwent full throttle training on Monday in his bid to be back into Australia's XI at the Waca.

The fixture has served Australia well in this instance, allowing Faulkner to ease his way back after a month out against minnows rather than a Test nation.

He then has a high-pressure clash against Sri Lanka on Sunday, followed by a match against Scotland to build his match fitness before the start of the knock-out phase.

It's unclear whether Faulkner will be able to deliver his full quota of 10 overs, though the likelihood of him having to do so against the Afghans is diminished.

"Hopefully, it [the time off] won't have much of an impact at all," Faulkner was quoted as saying.

"Three or four weeks, you can look at it in different ways. It has given me some time to freshen up and get my body feeling good again and hopefully, it holds me in good shape come the end of this tournament.

"I was batting five or six days after the injury and although they told me to ease back on it in the first two weeks, I was pretty much going 100 per cent which was a good thing.

I think I was lucky being a left-arm bowler and a right-hand batsman. It wasn't the same side when I was batting."

Despite an average of 48 with the bat, Faulkner will not be playing as a specialist batsman against the Afghans. "I'm pretty sure that I'm going to be picked as an all-rounder," he said.

"I'm not too sure how many overs they want me to bowl. I don't want to try and get too far ahead of myself."

"I'd be lying if I said I was not frustrated at the start.

"Any time you get injured is a shocking feeling and to do it at the time it happened, the same like last time before the World T20, was obviously quite hard to take at the start.

"I could not do much about that except continuing my rehab and I have been in good hands with the physios and team doctors to get me back in this position. Hopefully it all pays off.

On the other hand, young speedster Pat Cummins is in doubt for Australia's next two matches after his latest injury scare.

Unlike previous episodes, however, Cummins' latest injury is not serious. He will miss days rather than months after suffering what Cricket Australia described as a "niggle" in his left side after the game against New Zealand on Saturday.

Cummins was sent for precautionary scans which "showed nothing serious", CA said. "He will be monitored by medical staff this week to determine his availability for this week's matches."

While he has not been ruled out against Afghanistan and Sri Lanka, no risks will be taken with Cummins given his injury record and value to the team.

Cummins played an important role with both bat and ball in Australia's fightback against the Black Caps, making an unbeaten seven and then taking two wickets from his 6.1 overs.

He sent shudders around his country on Saturday when he tumbled after losing his footing in his delivery stride, but the injury is not related to that fall.
