Calcutta: With captain Michael Clarke’s fitness still a concern, Cricket Australia on Thursday added Shaun Marsh to their squad for the opening Test against India starting on December 9.

“The National Selection Panel has today advised that West Australian Shaun Marsh has been added to the Test squad as an additional batsman for the first Commonwealth Bank Test,” Cricket Australia said in a statement.

Clarke's hamstring injury remains a concern and it is still not clear whether he would be available for the opening match of the series, which required rescheduling owing to the tragic death of Phillip Hughes.

The Australian team, which is still recovering from the shock of Hughes' death after being hit by a bouncer, on Thursday flew from Coffs Harbour to here following an emotional funeral of Hughes in Macksville Wednesday.

Marsh’s addition to the Test squad, which is now 13-strong, raises the prospect of him and Mitchell Marsh becoming the first set of brothers to play Test cricket for Australia since Steve and Mark Waugh in October 2002.

Clarke had been recovering from the injury.
