Yasir Shah is expected to be fit for the day-night Test between Pakistan and Australia in Brisbane.
Shah has been struggling with a back injury in the build-up to the game, which is the first in a three-Test series.
However, Pakistan coach Mickey Arthur says the leg-spinner is making steady progress, despite teenage spinner Mohammad Asghar being called into the squad as cover.
"Yasir Shah is coming on nicely. He's come along really well," Arthur said.
"He bowled six overs the last day in Cairns [in the nets] which was pleasing. It will be good to see him go in the nets [on Monday], I saw him in the hotel and he seemed fine.
"He's obviously integral to our plans."
Former Australia coach Arthur says he feels he has something to prove as he takes on Steve Smith's side, over three years after being sacked in the build-up to an Ashes series.
"I wouldn't be honest if I said otherwise," he said. "That's what happens. It's a ruthless world out there.
"I always maintain that I loved the first year and a bit of it. It was outstanding and I felt we made some significant progress.
"This series isn't about me against Australia, it's about two very good cricket teams going head to head. I hope that can be the focus."
