It's time for me hand you back to Amy Lofthouse to take you through the remainder of the day.
She currently has no sound on her feed, though, so good luck.

England added 114 runs for just the loss of Dan Lawrence in that session.
They scored at 3.45 runs an over too.
England lead by 185 runs
England's session once again.
They are in complete and utter control.
Sri Lanka have put a sub fielder in at short leg, and first ball Joe Root is sweeping again. It's a lot finer this time and nowhere near the fielder.

This is reverse bodyline. Mendis is getting walloped at short leg.

Root has given Mendis a little touch to say he's sorry. And now he's hit him again! Oh dear.
Kusal Mendis has been hit again. Twice.
First time it hits the helmet/shoulder region, second time it is flush on the shoulder.
And he's going off this time. With three balls before tea, that seems sensible.

With Stokes, Pope and Burns all to come back into the side, any guesses on the batting line-up this summer?
James in Bristol
Lead by 184
Niroshan Dickwella was absolutely convinced that Jos Buttler had edged that. He was screaming, throwing the ball up in the air. I think he was excited by the take.
We'll have time for one more over before tea.

That would annoy me as a captain.

It is an absolute straight line.
Yeah, no bat.
Mickey Arthur is surprisingly calm in the changing room.
It's close to the bat but I don't think Jos Buttler has hit this.

Dickwella is convinced he's nicked this.
Niroshan Dickwella is absolutely convinced that Jos Buttler has nicked behind.
The rest of the Sri Lankans look less convinced.

I'd love to see England get 250 ahead, bat a few overs in the morning so Sri Lanka are thinking they will be in the field all day, and then declare. A real attacking statement.
Joel in Wigan
Lead by 181
Kusal Mendis is ok to continue, and first ball Joe Root is bringing the sweep out again, and Mendis is jumping and diving out the way again.
Mendis is in his 46th Test now - surely there's a newbie he can pass it onto? Problem is, he's very good there.
Jonathan Agnew
BBC cricket correspondent on Test Match Special
That has cracked into Kusal Mendis' wrist. Poor chap. He has taken all of that shot, and Joe Root hit it hard.
Lead by 180
Poor old Kusal Mendis has taken a fair few whacks at short leg today.
A few overs ago he got one on the end of the fingers from a Joe Root sweep and now he's got one on the wrist from another Root sweep.
The magic spray is out.
Root 165, Buttler 5
Just a single off Lasith Embuldeniya's 37th over. He's got figures of 3-128 now.
There's 10 minutes till tea.
