Australia fast bowler Nathan Coulter-Nile could miss the Ashes series against England after breaking down with another back injury. Coulter-Nile, who had been expected to be among four quick bowlers selected in the hosts' squad for the first test in Brisbane starting on Nov. 23, has been ruled out for an indeterminate period of time. "Nathan experienced some pain in his back following the two-day tour match against England last week," Cricket Australia's Sports Science and Sports Medicine manager Alex Kountouris said.
