Surrey youngster Ollie Pope made a confident start with an early boundary but fell for 10 in the 20th over to make it 75-3.
From the first ball of the next over, Keaton Jennings also departed, also caught behind, this time off Jasprit Bumrah.
Let's just go through this again. The first England wicket fell in the 12th over, Alastair Cook caught behind for 29 to leave his team on 54-1.

You can't escape the fact that at the moment if Root and Bairstow don't get runs then England are in the mire.
Let's just remember, we started the day with India on 307-6, England polished them off and conceded only 22 runs, then reached lunch on 46-0. They have now been dismissed within a session to concede a first innings lead of 168.

Between 1938 and 2016 England were never bowled out in a session. It is the third time in last two years it has happened.
Buttler c sub b Bumrah 39 (Eng 161 all out)
It's all over now though. Buttler backs away and launches it towards long on but does not time it and the fielder rushes in from the boundary to take the catch.

For a day and a half, Trent Bridge has been respectful, rather than boisterous. Not like the energy we saw at Edgbaston, especially when you consider this match started on a Saturday. I was told by some fans that sat in the Smith Cooper Stand that stewards were clamping down on songs and chants. Surely not?
Buttler 37, Anderson 1
A perfectly calm forward defensive shot and the crowd erupts.

This 10th-wicket stand is England's second-highest of the innings.
170 behind
A second six for Buttler, launching Ishant over long-off in expansive fashion and once again Jimmy will have just the one to face. Can he hold on again?

The final ball of the over is like that soul-destroying one that got him from the penultimate ball of the match against Sri Lanka in 2014. It is short and fended away.
177 behind
Pandya is taken off after a devastating spell of six overs, one maiden, 5-28. It is the quirky Bumrah who returns, looking to add to his one wicket. Again Buttler takes a single from the fifth delivery.

Buttler 29, Anderson
There are a four slips and a short leg and it is a beauty that swings and beats the edge, but there is no touch and Jimmy survives.
178 behind
Buttler has raced to 29 but he has given Jimmy one ball to face from Ishant.

This is pure theatre. Complete silence as the bowler runs in, then cheers no matter what happens - an Anderson block, a pinched single or, garnering the most noise, a Buttler biff.
181 behind
Excellent work from Buttler, he strikes a two and then plays a dead bat to the final ball and they race through for a single to allow him to retain the strike. We can go on for an extra half an hour in this session. It was extended by half an hour as it was. Tea could be as late as 16:40 BST if these two hang in there.
184 behind
Jimmy made 81 against India on this ground four years ago so you never know and he scampers through for a single to give Buttler the strike with three balls remaining in the over.
