India spinner Harbhajan Singh will play his 100th Test match this weekend, when he runs on to face Australia in the first Test in Chennai, it was confirmed on Thursday.

The spinner, often in and out of the side in recent years, made his debut in 1998 against Australia, and has taken 408 Test wickets.

More recently, India have opted to use Pragyan Ojha and Ravichandran Ashwin as their spin twins, with Bhajji appearing if an injury occurs, or if three spinners are required.

The spinner said of the occasion: "It's a big game. [The previous] 99 are gone. Obviously a bit nervous but I am sure I will be fine. I have faced these situations before.

"I have gone through times when I was not doing well or when I was doing well and got too excited. These things happen. Bit nervous to start with, but I will be fine.

"Once I get away with 100, we will see what needs to be done to play another 50-odd. Probably I will have to work even harder."
