David Warner's fractured thumb hasn't healed but he's prepared to risk long-term damage to open the batting for Australia in Friday's first Test against India.
The courageous left-hander says he's very confident of playing despite being hit by teammate Mitchell Johnson during a lively net session at the WACA last month which ruled him out of the one-day series against West Indies.
"I have a crack in the joint," Warner told reporters in Chennai.
"Where the joint moves, in the corner I have cracked that part, which in the healing process can be worse if it's aggravated and if I put cortisone in there.
"They've told me if it keeps moving around it won't heal properly and it can affect me down the track.
"So I might not have that range of movement in that joint for a long time.
"The precautionary thing we have done is keep it in the splint. (I) did some mobility stuff the past few weeks.
"It is painful but it is a process I am ready to go through to get through the first Test match."
Warner said on Tuesday he'd batted for one hour for four consecutive days and done some light fielding drills.
"I have iced it every time after training. It has been sore, yes, but that's what is going to happen with a break," he said.
The big-hitting NSW batsman said he'd received medical advice that his recovery time would be three to four weeks.
"It's now coming up to the end of the third week and it is still pretty sore," he said.
"I am having a full training session (on Wednesday) in the field so I will know then 100 per cent if I can catch balls.
"I have a splint that I can use when I'm in the field which protects the thumb and while I'm batting.
"At this present time, I am 100 per cent ready to go.
"There is a rubber piece which sits at the end of the thumb.
"I have a guard that sits halfway underneath and covers the top part so if I get hit, it gets protected."
Warner said he was hit on the left thumb while batting in the nets on Monday -- by a spinner.
"A lot of keepers keep with broken thumbs and fingers and they are calling me weak," he said.
"It is painful to bat with but I am prepared to put up with the pain to play for my country.
"I reckon I can do my job for the team and that's what I will set out to do."
