That looked good from here. I'm trying to think of a way he might be spared. The crowd are hoping that it might be too high. It looks plumb to me.

Full, straight, bang in front on Mehedi's pad. He has to review but I think this is going to be out.

Sabbir has potentially taken this game away from England. In his maiden Test, under this pressure, he has shown enormous talent. Fabulous batting.

This last sessions has been a slow-burner, it's gripping.

Mehedi is off the mark with a swept single. I bet his heart is threatening to thud its way through his rib cage. Sabbir survives a huge appeal for lbw from Bairstow. Only one review left and Cook isn't prepared to let the keeper use it.

Sabbir has the last word, though, driving down the ground for a four that brings up his maiden Test half-century. He is the man on whom Bangladesh's hopes rest.

I think Cook will think that he'll now stick with Batty and Stokes is the next cab off the rank to keep things tight from Broad's end.

We've got shadows lengthening across the pitch, a batting team who can't really risk digging in and a bowling team on the attack. If my hands weren't otherwise engaged typing this, I'd have chewed down to the wrists by now. 

Sabbir has charged through the gears. He swings at Broad and whips to leg for two but can't connect with another couple of filthy swipes.

Suddenly, this pitch is spitting like Frank Rijkaard at the 1990 World Cup.

What a finish we have on our hands now. Would you fancy being 18-year-old Mehedi now? He is out to join Sabbir. A lot on his shoulders.

Bounce is the killer. That one went through the top, popped up and credit to Ballance who made some room for himself to tumble to his right and take a fantastic catch. Mushfiqur is distraight, dragging himself from the pitch.

Batty is back. He concedes an early boundary, though, as Sabbir cleverly drops to one knee and helps it round the corner and past leg slip. The stadium is rocking now.

Tim Burt: The best spinner of last summer - Jack Leach - must be watching this with some justifiable frustration. 

That is a brute of a ball from Broad. It is a yorker that the bowler thinks has hit Sabbir on the pad before flying past Bairstow for four. Cook waits an age so that when the review comes it is too late. Broad is furious. I think he was waiting for the umpire's signal before deciding to review. In actual fact, the ball appears to have hit nothing so Cook's hesitance has saved a review. Still four runs off those required, though. This is slipping away from England.

The next move would be for Batty to go round the wicket to the right-handers.

Superb shot from Mushfiqur, who pulls Broad's short ball through mid-wicket for four.

Batty is warming up.

Three easily accrued singles for Bangladesh with sweeps and pulls to leg off Rashid. They'll be more than happy with that. Mushfiqur takes a little risk with a last-ball long hop but his aerial cut lands safe for another run.
