Pat Cummins sidelined until World Twenty20

Australia paceman Pat Cummins is unlikely to be fit until at least the World Twenty20 in India next year as he battles to recover from a third stress fracture in his lower back in three years.

The 22-year-old has endured a terrible run of injuries since playing in his sole Test match against South Africa in 2011.

His latest back problem comes after he had enjoyed a rare injury-free period over the past year, although he has shrugged off this fresh setback.

"I'm not really worried now, compared to a couple of years ago," Cummins said.

"The fact I was able to come back after bowling a heavy schedule over two years, and to have it culminate in a really successful one-day international series at the back end of it means I'm not worried at all.

"I know I can do it. While we haven't set out a rehab plan yet, and things will obviously be dictated by my recovery, the Twenty20 World Championship in India early next year has been targeted as a goal for me to try and return for.

"I will be doing all of my rehab sessions with that tournament in mind."

The World T20 will be held in India from March 11-April 3, meaning Cummins is set to miss the whole of the Australian season and the tour of New Zealand in February.

Cummins was named in Australia's 15-man squad for the two-Test tour of Bangladesh next month but has been replaced by fast-bowling all-rounder James Faulkner.

Faulkner, 25, played his only Test for Australia in 2013 and is hoping to be able to pull out his baggy green Test cap again in Bangladesh.

"I get [my Baggy Green] out every now and again and have a look at it but there might be a little bit of dust on it because it's been a good couple of years," he said.

"It's a different feeling and I've only got the taste once, but it was enough to keep driving me to get back into the squad and hopefully I can get an opportunity again and do well."

Faulkner is likely to be competing for a place with Mitchell Marsh and Glenn Maxwell but he believes all three of them could play together.

"I think most teams around the world now are playing two or three all-rounders so there's no reason why we can't all play together especially in those conditions as well," he said.
