Michael Clarke confident of Ryan Harris fitness

Australia captain Michael Clarke has said that he is confident fast bowler Ryan Harris will be fit for the third Ashes Test match in Perth.

The hosts lead England 2-0 following victories in Brisbane and Adelaide, meaning that victory at the WACA will see them lift the urn for the first time since 2007.

Harris has been struggling with a knee injury of late, placing James Faulkner, Doug Bollinger or Nathan Coulter-Nile on stand-by.

"I'm hopeful that everyone will come up, I think there's the obvious one in Ryan-o, who bowled today, and we'll see how he pulls up," Clarke told reporters. "I'm confident he'll be fine.

"I think one of [Faulkner, Bollinger or Coulter-Nile] will come in and replace Ryan if he's not fit but, as I say, I'm very confident that Ryan will be okay."

The third Test gets underway tomorrow.
