The BCCI has now confirmed what Kuldeep Yadav hinted at earlier.

Spinner Ravichandran Ashwin will return to the Test today, having left before day three for a family emergency.

"The team management, players, media and fans have shown immense understanding and empathy, acknowledging the importance of family as a priority," the BCCI said.

"The team and its supporters have stood united in support of Ashwin during this challenging period, and the management is delighted to welcome him back to the field."

Fantastic intent from Kuldeep, smacking Hartley back down the ground for four.

He then tries an elaborate reverse sweep that doesn't come off - the ball strikes him on the pad but he was well outside the line and England's appeals die in their throats.

Ah, here's that change as Mark Wood replaces James Anderson.

He storms in from around the wicket and Kuldeep squeezes him to point for a single. Gill then takes his own run with a push to the leg side.

Into the ninth over of the day and no change in the England bowlers yet, as Hartley continues.

The India batters work him for three singles.

Lovely classic drive from Shubman Gill, sending Anderson's final ball rocketing to the cover boundary.

And with that India's lead passes 350.

A first four of the day for Gill, pulling a low Hartley delivery to the ropes.

He then takes a single to move to 77.

All pretty comfortable for the India batters so far.

Gill cuts Anderson down to backward point for a single, making his ground at the bowler's end with little more than a gentle stroll.

It's enough to enthuse the crowd, again featuring a lot of children, who seem to get excited by anything that reaches the outfield.

Ooof, a rank long hop from Hartley to finish his over and Kuldeep doesn't need asking twice, clouting it to the boundary in front of square.

This was the ticket office around 30 minutes before the start of play. The most expensive ticket in the stands in 300 rupees, so just under £3. Hospitality comes in at 1200 rupees.

Gill pushes Anderson for a single to point, the sole run from the over.

Kuldeep displayed some aggression in the previous over, but there's no real reason for India to take any risks in the first hour today.

Kuldeep has complete licence to play big shots. India will be keen to press on positively towards, what, a 500-run lead? Have England batting by mid-afternoon.

Huge from Kuldeep Yadav!

He steps down the pitch to hoik Hartley's final delivery over long-on.

That's his first six for India.

It's James Anderson at the other end for England, bowling with just one slip in place.

Gill cuts him for one, bringing up the India 200.

In his interview before playing, Kuldeep Yadav suggested Ravichandran Ashwin is going to return to the Test.

He missed day three for a family emergency.

"I am not sure but I think Ash bhai is coming back," Kuldeep said.

He also said Yashasvi Jaiswal, who retired hurt with a back issue yesterday, is "feeling much better".

On the match situation, Kuldeep said: "Close to 400 is a good total. On day five it is not that easy to chase. We are getting a lot of purchase on the surface."

Shubman Gill takes a single from the first ball of the day, pushing one to mid-off.

Kuldeep also gets going for his first delivery, slipping one down to the fine leg region.

Tom Hartley's going to open the bowling for England.

Shubman Gill resumes on 65, while Kuldeep Yadav, in as a nightwatchman for the second time in this match, is on 3.

Let's get cracking.

Our chief cricket writer Stephan Shemilt summed up England's woes yesterday.

"Making sense of the highs and lows of this England team is harder than putting spilled milk back into the bottle. The highs have become regular and often mountainous. They make the lows all the more unfathomable."

Take a read here.

Was yesterday the worst day of the Bazball era? It's certainly up there.

Having dominated India on the evening of day two, England collapsed from 224-2 to to 319 all out, before the hosts moved with little trouble to 196-2 at the close, a lead of 322.

If England are to stand any chance at all of chasing India down then they need early wickets - they've struck on the mornings of day one and two, so it could happen again. But if Rohit Sharma's side survive the session they will have likely reached a total that England will find near impossible to chase, even in their aggressive pomp.

Good morning.

For most of us, the next few hours will be of little consequence, the majority tucked up under duvets or idly scrolling their phones on some foreign shore.

But for the England side the following session is absolutely vital, not simply because it will decide this match, but because it may set the tone for the remainder of the series.

Time to step up.
