Australia’s Ashes trumpcard Ryan Harris says his brittle body could “snap” again at any time.

And the 34-year-old fast bowler concedes he’s likely to get another serious injury – he just hopes it comes after the looming Ashes series.

“I could snap … who knows,” Harris said as he made a successful return to long-form cricket for Queensland in a Sheffield Shield match against South Australia in Adelaide.

Harris took 3-42 from 23 overs in his first-class comeback after tearing a hamstring injury in England two months ago.

Harris’ injury came at the end of his stunning away Ashes series which reaped 24 wickets at an average of 19.58 in four consecutive games – his longest continuous stretch of Test cricket.

Harris became the leader of Australia’s pace attack in England but said he still had “issues with all my body, tendons and stuff”.

“I’m probably going to have another major injury before I finish. I just hope it’s not in the next six months,” he said.

Harris’ hamstring strain added to a personal injury list featuring a chronic knee problem, fractured ankle, shoulder concerns, back strains, hip pain and Achilles soreness.

But he said any pain was diminished by the prospect of a home Ashes campaign.

“I have laid in bed a few nights and tried not to think about it … but if I have got the new ball at the Gabba in the first over, it’s going to be pretty exciting,” he said.

“If we play well, I think we’ll beat them, as simple as that. We have just got to make sure we play consistently.”

Harris hoped his close mate and fellow quick Mitchell Johnson, who has found form in the current one-day series in India, was selected for the Ashes.

“It’s so good to see him bowling fast and with swing and scaring the Indians. And he’d do the same to the Poms I think,” he said.

“He copped a lot of stick a few years ago, especially over in England.

“And it would be great bowl in a partnership with him … and at the end of the series, sit there with a little Ashes urn next to us.”
