Marsh flying home under injury cloud

Australia will sweat on results of further scans on Shaun Marsh's shoulder after Glamorgan confirmed the Test batsman will fly home from his playing stint in the United Kingdom.

On the eve of his 35th birthday, Marsh injured his left shoulder after diving to stop a boundary in Glamorgan's T20 clash with Sussex at Cardiff on Monday. 

Scans have revealed he suffered ligament damage and disruption in his acromioclavicular (AC) joint, with the left-hander to miss the remainder of the Welsh county's domestic T20 campaign.

Cricket Australia confirmed Marsh will return home immediately for further scans, with a Test tour against Pakistan in the United Arab Emirates in October on the horizon.

Australia can ill afford to lose Marsh for that trip given the veteran's noted skill against spin bowling, which the Test team will expect to face plenty of on the subcontinental tour.

The Aussies are already without three first-choice batters for the Test series; Steve Smith, their best player of spin, David Warner, who struck two centuries in his last two Tests in Asia, and Cameron Bancroft, who, while uncapped on the subcontinent, was the leading run-scorer on the red-ball leg of Australia A's 2015 tour of India.

While Glamorgan have fellow Australian Usman Khawaja on board as their second international player for the T20 competition, director of cricket Hugh Morris said they'll explore an overseas replacement for Marsh.

"As a proven international batsman, Shaun will leave a big hole at the top of the order and we are currently considering our options and are looking at options for replacing him for the rest of the season," said Morris.

Marsh is coming off a superb Test summer, hitting two centuries against England in Australia's 4-0 Ashes victory while he added another two tons against England last month after a recall to the ODI team.

The Western Australian has suffered has suffered frequent injuries throughout his career, including chronic back and hamstring problems, while he also required surgery on his left elbow in 2014 that kept him out of action for several months.

Marsh begun his stint at Glamorgan in style with an unbeaten of 111 on debut, but managed just one half-century from his following six first-class innings. He struck 10 and 15 in his two T20 knocks for the club.

Paceman Marchant de Lange is also likely to miss the remainder of Glamorgan's T20 campaign.

"Losing Marchant for the rest of the competition and in Shaun's case, the season, is a big blow," Morris continued.

"Marchant was one of our best bowlers in the T20 competition last year and is an inspirational character in the dressing room, however we have a strong bowling line-up and I'm sure we will be able to fill that gap with the players we have available."

Glamorgan sit second on the county T20 standings with one win and one loss so far.
