Perth Scorchers strike bowler Nathan Coulter-Nile has been ruled out of the entire Big Bash League series with his injury ravaged playing career now hanging by a thread.
The explosive paceman has new stress fractures in his lower back and will be forced to the sidelines for at least nine months and possibly even out of playing rest for up to a year.
Coulter-Nile, 30, had scans late last week as he made a desperate bid to prove he was fit for a return to Big Bash Twenty20 action in Perth's New Year's Day clash with Sydney Sixers at the WACA.
He is headed for a full rehabilitation program and hard decisions on whether to continue attempts to play again at the highest levels.
His future as a limited-overs and T20 player are also understood to now be under threat with continued injury breakdowns for the paceman.
Coulter-Nile reported a return of chronic pain in his back after what appeared a successful playing comeback with his WACA club team Subiaco-Floreat on December 23 when he completed four overs and batted for almost an hour untroubled.
It is the third bout of nagging back pains for the aggressive speedster in the past four months as he pressed to reassume his playing career.
Coulter-Nile is considered a limited-overs and T20 specialist with world class performances at times with Australia, his home base Scorchers and in the high tempo Indian Premier League.
He earned a lucrative Cricket Australia contract in the region of $280,000 back in October after his highly successful return to the national limited-overs team in India.
He has suffered a horrible succession of back, hamstring and shoulder injuries in the past two years after the energetic paceman had secured his status as one of the nation's premier limited-overs bowlers and hard-hitting lower order batsman.
He has played 21 one-day internationals and 19 T20s for Australia.
Coulter-Nile clutches his right shoulder after dislocating it while fielding for the Perth Scorchers in the Big Bash League back in 2015.
Coulter-Nile started this Australian summer on the verge of a stunning Ashes Test debut after another extended injury recovery last year.
He was plucked from a highly successful training schedule with Western Australia and back into the national limited-overs team for a series of one-day internationals against India in October.
He burst back into first-class ranks with an exciting all-round man-of- the match return against Tasmania in Perth in late October with 1-23 from nine overs and 3-18 (six overs) of fiery fast bowling as well as 42 and 52 batting at number nine.
Coulter-Nile was withdrawn from his WA first-class team and captained a state Second XI in England's Ashes tour opening two-day game when he sent Test batting great Alastair Cook packing for a second-ball duck.
It appeared at the time that Coulter-Nile was headed to join Australia's front-line pace battery Mitchell Starc, Josh Hazlewood and Pat Cummins for Ashes duties this summer.
Perth Scorchers will face off against the Sydney Sixers at the Furnace on Monday evening.
