Kohli hits defiant ton

Stand-in skipper Virat Kohli survived a fearsome blow on the helmet from a Mitchell Johnson bouncer as he scored a defiant century to keep India in the first Test against Australia Thursday.

Kohli was heavily struck by the first ball he faced from Johnson, briefly setting nerves jangling following last month's freak death of Australian batsman Phillip Hughes.

But he went on to register his third Test ton against Australia as India reached 369 for five at stumps on Day Three, trailing the hosts' overnight first-innings declaration of 517 for seven.

Kohli was out for 115, three overs from stumps, when he hooked Johnson to Ryan Harris at fine-leg.

Rohit Sharma was not out 33 with wicketkeeper Wriddhiman Saha on one, after surviving a Johnson peppering, to place the tourists 148 runs behind with two days left.

It was Kohli's second Test hundred in Adelaide after his 116 almost three years ago at the famous ground.

The tourists easily negotiated the follow-on target of 318 on the placid Adelaide pitch to raise hopes of taking an innings lead.

It didn't start well with Kohli ducking into the path of Johnson's menacing bouncer, which thudded into the front of his helmet.

After a few moments of concern from the fielders, the Indian captain continued. Australian batsman Hughes was fatally struck by a rising ball late last month, plunging the cricketing world into mourning.

"I went to Virat and asked him if he was all right, and first we checked the helmet to see if there was any damage but it was fine," batsman Cheteshwar Pujara said.

"He batted really well, forgetting about that particular ball. His innings was very crucial for us and it was fun to watch."

While Kohli went on to reach three figures, Murali Vijay (53), Pujara (73) and Ajinkya Rahane (62) all wasted good starts, failing to emulate Australia's three first-innings centurions -- Steve Smith (162 not out), David Warner (145) and Michael Clarke (128).

"It was a great breakthrough with Virat's wicket and it was good to see Mitch get some reward for some pretty hard toil with the ball," Australia spinner Nathan Lyon said.

"If Virat doesn't play that shot and they're still four down it probably leans towards them."

Kohli is captaining India in the absence of wicketkeeper MS Dhoni, who is recovering from a hairline fracture of his thumb and is expected to resume his post for next week's second Test in Brisbane.
