Australia opener David Warner has conceded he is still being hampered by the neck injury he picked up in a training drill two days out from the first Magellan Ashes Test match.
Australia entered the Test with their expected XI despite Warner and Shaun Marsh (back) being under a cloud on match eve.
During a rain break that delayed the start of the second session in Brisbane, Warner told Wide World of Sports' Ian Healy he was still in pain but was "good to go".
"It's literally a pain in the neck but I was always going to be up for it, a few painkillers here and there, but I'm out here now and I'm roaring," Warner said.
"I've chased a few to the boundary, which hasn't helped.
"But a bit of adrenaline, a few drugs in the system and it's good to go."
Australia's opener added he was "trying not to look up" as teammates threw him the ball at mid-off on its way back to the bowler, before adding the injury was still making it "quite hard" to bat in the nets.
"It was a bit bizarre. I've never really had a stiff neck. It's sort of gone down the spine per se but it is quite hard getting out there in the nets and trying to face up.
"I've got the old Shiv Chanderpul and the JL (Justin Langer) front-on look at the moment.
"But look, I'm looking forward to getting out there and facing the challenge that's for sure."
Warner later underlined how the injury was not impacting his play, with a brilliant diving stop from mid-off to save a boundary off the bowling of Nathan Lyon.
Warner added that Marsh's back injury had taken the playing group by surprise but said the recalled veteran was "ready to go".
"We didn't know until it (news of the injury) got out," Warner said.
"He's obviously had a bit of a history there. He said he's ready to go, I think he's had a jab and he doesn't look as stiff today."
