RPT-UPDATE 1-Rugby-Sharpe to take 'cursed' Wallabies captaincy

(Refiles to clarify Deans as Australia coach in 2nd para, no

other changes to text)

* Sharpe third captain this test season

* Beale dropped to bench for second time

Sept 11 (Reuters) - Veteran lock Nathan Sharpe has been

named to lead Australia against Argentina in their Rugby

Championship clash on Saturday, after the Wallabies' 'captain's

curse' struck a third time this season with stand-in skipper

Will Genia ruled out with injury.

Sharpe had planned to retire after the Super Rugby season

but was persuaded by Wallabies coach Robbie Deans to play on in

the southern hemisphere tournament.

He now founds himself captaining Australia for a third time

in his 109th test after previously leading the side against New

Zealand in 2004 and Samoa the following year.

Sharpe takes the reins from scrumhalf Genia who ruptured a

knee ligament in the Wallabies' 26-19 win over South Africa in

Perth on Saturday and has been ruled out for the season.

Genia had taken the captaincy from flanker David Pocock, who

also suffered a season-ending knee injury against New Zealand in

their first match of the championship.

Pocock had in turn taken it from regular captain James

Horwill, who was ruled out of the test season when he sustained

a serious hamstring injury during the Super Rugby competition.

"To have the privilege of leading Australia in the first

ever test to be played on the Gold Coast is an experience I will

always treasure," Sharpe said in a statement.

"It's important we keep our focus as a team, build on what

we achieved last weekend in Perth, and add to that momentum.

"No one else in the squad has played Argentina before but I

have and they will be tough, incredibly passionate and

uncompromising.

"You only have to look at what they have achieved to date in

their tournament matches to see what a threat they will be."

After being belted by South Africa 27-6 in their tournament

debut in Cape Town, Argentina held the Springboks to a 16-16

draw at home and impressed the All Blacks with their resolve in

a fighting 21-5 loss in Wellington.

Deans has had to reshuffle his team constantly this season

due to injuries and he sprung a surprise by shifting inside back

Berrick Barnes to fullback in place of Kurtley Beale, who was

dropped to the bench.

Barnes started the test season against Scotland at flyhalf

and has played inside centre against the All Blacks and

Springboks, but has never played fullback at international

level.

New Zealander Deans said Barnes's goalkicking this season

had earned him the start.

"Berrick has good grounding at the back while his ability to

take just about every point-scoring opportunity on offer was

highlighted once again last weekend," Deans added.

"His presence provides good balance to the backline, while

giving us the opportunity to throw Kurtley in where he will be

at his most dangerous, against a tiring defensive line as the

game opens up and he can get out there with a license to play."

Beale, widely considered one of the best attacking players

in world rugby, has suffered a crisis of confidence during the

Rugby Championship, with Deans now dropping him twice from the

starting side.

The return from injury of inside centre Pat McCabe, whose

hard-running style is preferred in the position by Deans, may

have also played a part in the backline reshuffle.

Nick Phipps takes over from Genia at scrumhalf, while lock

Kane Douglas makes his test debut in place of Sitaleki Timani,

who suffered a hamstring injury against the Springboks.

Stephen Moore, a late withdrawal from the starting side

against the Springboks, has been bracketed with Saia Fainga'a on

the replacements' bench and could earn his Australian record

73rd cap for a hooker if he is passed fit from his hamstring

injury.
