Australian opener David Warner has admitted his neck is still causing him discomfort, despite taking his place in the side and being cleared fit to play in the first Test against England.

Warner picked up a neck injury during a catching drill at training two days ago and has undergone round the clock treatment to ensure he is fit for the opening Test of the Ashes series.

Warner, along with Shaun Marsh who was also under an injury cloud (back) was named in XI, but said on Thursday he is still hampered by the injury.

However, despite the discomfort, he told Channel Nine during the first day's rain delay that he is ready to bat regardless of the mild neck issue.

"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.

"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.

"But look, I'm looking forward to getting out there and facing the challenge that's for sure."

England has reached 1/95 midway through the second session on day one at the Gabba.
