Smith should captain all forms: Harris

Recovering quick Ryan Harris believes Steve Smith should be handed the Australian captaincy across all forms of the game.

Harris, who is racing to be fit for the Boxing Day Test after injuring his quadriceps in the first Commonwealth Bank Test, insists is makes sense for Smith to lead Australia to the ICC World Cup if Michael Clarke fails in his race to be fit for the tournament.

"There's no doubt I can see him as captain in all forms," Harris told Fox Sports.

"We will see what happens, there is obviously a big (2015) World Cup coming up.

"George Bailey's done it (ODI role) in the absence of Michael Clarke and I think he has done a pretty good job.

"But with Steve Smith heading that way it might be a good idea to give it to him."

Smith stood tall in his first Test as captain, notching a game-changing 133 before fiery quick Mitchell Johnson sealed a four-wicket win at the Gabba with a day to spare.

Quick Single: Selectors consider third Test changes

Harris claimed he was a "90 per cent" chance of returning in the third Test in what loomed as a straight swap for left-arm speedster Mitchell Starc.

"It's going well. It was just a slight strain there," Harris said.

"There's no pain there – it's all looking up.

"I am pretty keen to get back out there and play – I am frustrated watching."

Selectors are unlikely to risk allrounder Mitch Marsh, who was limited to batting in Brisbane after suffering his fifth hamstring injury in two years while bowling on day one at the Gabba.

Marsh's injury may fall in Shane Watson’s favour after the 33-year-old suffered a double failure in Brisbane batting at No.3, including an ugly eight-ball duck on Saturday.

Watson has a 2014 Test average of just 23.

However, he looked dangerous with the ball in Brisbane, taking match figures of 1-66 off a total of 27.4 overs – the most he has completed in a Test in two years.

Allrounder James Faulkner may replace Marsh after being on standby for the WA matchwinner in the recent ODI series against Pakistan.

But the form domestic batsman is ex-Test opener Ed Cowan (Bupa Sheffield Shield high 590 runs at 65.55 with four tons).

Scan results will reveal the full extent of David Warner's ailment although a team spokesman claimed they did not believe he had suffered a thumb fracture.
