Aussies keep concussion sub options open

Australia won't be caught short if a concussion substitute is needed despite releasing two Test squad members to domestic duties, captain Tim Paine says.

Fast bowler James Pattinson and batsman Cameron Bancroft are departing the Test squad to play Pakistan in Adelaide from Friday.

The pair will play in Sheffield Shield games also starting Friday - Bancroft for Western Australia against South Australia in Perth, and Pattinson for Victoria against NSW in Melbourne.

Queenslander Michael Neser will remain with the Australian squad for the duration of the Adelaide Oval day-nighter against Pakistan.

Should Australia require a batting concussion substitute, they're likely to summon Bancroft while Neser looms as a potential bowling substitute.

"Bangers is a couple of hours away on a plane, if something happens we will be able to get him back pretty quickly," Paine told reporters on Thursday.

"I think you have got 24 or 36 hours to replace a concussed player so we will have plenty of time to get someone back whether it be a batter or a bowler..

"I don't think Nes will be batting in our top six but he is a real handful with a pink ball and if something was to happen we will know Nes will do a great job."

Australia have been forced to call on a concussion substitute once, when Steve Smith was ruled out of the second Test against England last August.

Marnus Labuschagne was drafted into that Test, made 59 in the second innings and has held his spot in the team since.
