Former Australian captain Ricky Ponting says half of the current squad may never play again.

Ponting says that after Australia's Ashes debacle, as many as eight members of the current squad will not play Test cricket again.

"I had a bit of a think about the squad to plan ahead and think about the future and ... I thought there could be eight guys who might not ever play Test cricket again in this touring squad," Ponting said.

"Rogers is retiring. Harris has already retired. You'd think it'd be hard for Haddin to get back in now at his age.

"You could probably say the same things about Watson - is Watson going to get back in at his age? I'd like to think so because I still think he's got some good cricket ahead of him."

Punter did not name the other four players who he believes may face the chop.

"There are a few others - that might do me," he said, not wanting to cause a stir.
