Live updates: Australia vs India, second Test, day two at Adelaide Oval

So Australia takes a lead of over 150 - that's going to be massive in this contest.

You do not want to go anywhere in the next couple of hours.

The conditions will be perfect for bowling with this pink ball.

India only managed to get one wicket last night in similar conditions.

Australia will be hoping that they can get a whole lot more.

Light up bails fly everywhere as Siraj gets the ball straight through Boland.

Boland takes off faster than if he's going for a run - racing to the dressing room to get himself in the mindset for bowling.

Lyon misses the first that flies through to the keeper.

Now he drives past diving mid on and they are going to run three.

Three slips, Bumrah bowls an inswinger that Lyon defends. It was a no ball.

Now it's a shorter ball that rears up and hits Nathan Lyon on the forearm. He has a pad there, but even so. Nasty blow.

Down the leg side, Lyon swishes, but misses.

Another hooping inswinger, Lyon gets an inside edge and gets a single for it too.

Outside off, Boland swings and misses.

Lyon and Ashwin have a friendly chat that leaves them both smiling.

BEATEN! What a ball! No chance that Scott Boland was going to get anything on that, the ball seaming away and beating the outside edge.

Good stride from Boland, and he leaves the ball outside off.

BEATEN! And he prods forward this time and the ball beats the outside edge.

Siraj gets a wicket first ball of the final session!

It's a tame end for Starc, who just scoops the ball to mid off.

He departs for 18 off just 15 balls.

Another very, very eventful session in the books at the Adelaide Oval and it is Australia in firm control.

That middle session was owned by Travis Head, who pounded yet another brilliant century on his home ground.

His innings was eventually brought to an end by Mohammed Siraj, who might have something to answer for after giving Head an almighty send-off.

Here's what Stuart Clark had to say about that on ABC Radio.

"I dare say Mohammed Siraj is in a little bit of trouble for what appears to be giving Travis Head an old-fashioned send-off."

"Arms waving. Oh no, you can't do that. I don't know what the rules are. I'm pretty sure he can't do that anymore."

Australia heads into the dinner break with a very, very handy 152-run lead over India, who will be ruing their batting performance on day one.

Bumrah has figures of 4-59 off 22 overs, he's been brilliant once again.

More importantly from an Indian perspective, he looks to have shrugged off that cramp from a few overs ago.

Simon will be back with you for the start of play after this break.

The review checks the LBW as well, but it's done way too much and misses leg stump.

FOUR! Too straight from Siraj as he strays onto the pads from around the wicket and Head whips it away for four on the leg side. A real loosener from Siraj.

Siraj strays down leg side and Head plays and misses an attempted pull shot.

SIX! What a shot this is from Travis Head! It's not a bad ball from Siraj, it swings into middle stump, but Head in this form just picks it up and whips it into the stands. Outrageous stuff.

"That was almost a no-look six," says Kerry O'Keeffe on commentary.

FOUR! Siraj runs in to boos and bowls a full one outside off to Mitchell Starc, who pounds it through the covers for a boundary.

It's another in swinger but is onto Starc's pads and he whips it away for another single.

Travis Head is gone!

He lets the centurion know all about it, and Head bites back too before walking off.

Head receives a standing ovation from the crowd in at the Adelaide Oval.

Bumrah gets his line better and Head dabs it into the off side for a single.

A good ball on middle stump to finish off which Cummins defends down the pitch.

Massive concern here for India as Jasprit Bumrah pulls up.

It seems like he's dealing with some cramp in the adductor region in his left leg.

He's getting stretched out and is given some pickle juice but this is not good for India.

"I think he's got to go off. He's too big a component for this Indian side," says Michael Vaughan on commentary.

Bumrah's getting stretched out by the physio and Ravindra Jadeja is also giving him a little shoulder massage.

Bumrah has a smile on his face, so hopefully this isn't as bad as it looks.

He gets back on his feet and continues the over, and the whole of India breathes a collective sigh of relief.

India wastes no time taking the new ball and Jasprit Bumrah's number is dialled up.
