Batsman David Warner is confident of being named in Australia's XI for the first Test against India despite the limited movement of his injured thumb.

Warner was ruled out of February's ODI series against West Indies after fracturing his left thumb during practice.

He has since returned to facing fast bowling in the nets and will undergo a full fitness assessment on Wednesday, two days before the start of the series opener in Chennai.

"I am very confident of playing. I have had four long days of training. I have been hitting for an hour each session to get a feel of hitting the ball and putting myself under fatigue to see if I will get any pain as I go on," said Warner.

"I have iced it every time after training. It has been sore, yes, but that's what is going to happen with a break. They said to me initially three to four weeks, it's now coming up to the end of the third week and it is still pretty sore.

I am having a full training session in the field on Wednesday, so I will know then 100 percent if I can catch balls. I caught some balls at 50 percent and felt no pain at all. 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 percent ready to go."

The left-handed Warner, who will play with a protective splint inside his left glove, missed the two practice matches against India A and an India President's XI.

The 26-year-old is, however, determined to play through the discomfort in conditions he anticipates will require decisive shot selection and characteristic aggression.

"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," he added.

"I feel my game is better where I'm putting the pressure on the bowler. You've got to show intent, try and look to score, but that doesn't mean scoring off every ball. You have to respect the good balls, and when the ball is there to be hit, use your feet."
