Cowan, Starc out. Khawaja, Harris in.

Cowan and Starc are out of the test because of their bad performance last week.

Cowan only scored an embarrassing 0-14 last week at Trent Bridge.

Starc took some wickets, but was always bowling all over the place.

Harris's career has been mainly of injury, but he is a good pace bowler. The 33-year-old has taken 47 wickets at 23.63 from only 12 Tests and is capable of swinging the ball at high pace.Harris has not been in the cricket team since the third and final Test against the West Indies in the Caribbean last year.

Cowan's replacement, Khawaja, had been out of the cricket team since being dumped in late 2011.
He was set to play the third Test in India but was part of the so-called Mohali four who were suspended for not completing their homework. Khawaja, who made his debut in the final Ashes Test of the 2010/11 series, has played six Tests for an average of 29.22 and has not played since the loss to New Zealand in Hobart in December 2011.

Team: Shane Watson, Chris Rogers, Usman Khawaja, Michael Clarke (captain), Steve Smith, Phil Hughes, Brad Haddin, Ashton Agar, Peter Siddle, James Pattinson, Ryan Harris.
