Australia coach Mickey Arthur says paceman Ben Hilfenhaus will miss the second Test against Sri Lanka starting Boxing Day because of a side muscle strain.
Hilfenhaus, who sat out the third Test against South Africa in Perth earlier this month with a sore knee, took 1-30 from overs in Sri Lanka's first innings of the first Test at Hobart before breaking down with a side injury on Sunday.
Hilfenhaus made a duck in Australia's second innings and didn't take the field in Sri Lanka's second innings.
Arthur said it was uncertain how long Hilfenhaus will be out of action. Arthur "He's certainly not a starter for Boxing Day and we'll see after that."
Mitchell Johnson, named 12th man for the Hobart Test, is likely to be recalled.
