Michael Clarke passed fit for second Test

Australia vice-captain Michael Clarke says he is fit to play in the second Ashes Test against England in Adelaide after recovering from a back injury.



The second Test starts on Friday. But pace bowler Mitchell Johnson is expected to make way for Doug Bollinger after a poor performance in the drawn first Test.



England are set to stick with the same line-up from Brisbane.



Coach Andy Flower will also be able to play a full role after missing part of the first Test to have cancer surgery.



Australia's Clarke had an extended nets session today to prove his fitness and also worked with captain Ricky Ponting in an effort to regain his form after a disappointing score of only nine runs.



Australian media reports that pace bowler Johnson refused to take part in the nets session after being told he was being dropped to make way for Bollinger.



Johnson has played in 39 Tests but his figures of zero for 170 at Brisbane marked the first time he has failed to take a wicket in a Test.



The home side's only other selection worry is Ben Hilfenhaus, who has been suffering with a sore hamstring.



If he fails to recover in time his place could go to Ryan Harris, who is on the comeback trail after knee surgery.
