Lunch has been taken. It is not surprising. The stands have emptied very quickly and the few braves souls who have remained are hiding beneath umbrellas.

"The rain has got quite hard. The sky is dark and all the umbrellas are out."

It has been a mixed first session for England. Anderson has been superb, picking up two wickets. But when he is out of the attack, the home side have been lacking. Two catches have gone down, both from the edge of Mendis, who is 47 not out.

The rain is heavier. Looks like we may be getting an early lunch.

"He's spoken about as a top catcher, but that's not difficult. We all drop them but, as catches go, that's nice and comfortable. That's fairly regulation."

Another one goes down. Mendis attacks Broad and picks up four with a flick to leg. The bowler strikes back and thinks he has had the final word by catching an edge, but James Vince spills it at third slip. He should have taken it.

Mendis has been dropped twice now en route to his highest Test score.

To compound matters, here comes the rain. Off go the players and on come the covers.

"It will be much harder for England today. Stokes is injured, Broad hasn't been at his best and the conditions don't suit Finn. Sri Lanka will have learned from yesterday and you'd expect them to make a better fist of it today."

There is a hunt going on in the Western Terrace, complete with a pantomime horse and, bizarrely, a fairy. It all ends in an ugly pile-on of red jackets, felt hooves and tattered glittering wings.

Meanwhile, on the pitch, Finn drops to one knee to appeal for a ball that cracks into Chandimal's pads as he loses his footing. The ball was clearly going down leg, though.

Finn is looking a bit toothless.

Lancashire are supposed to begin their T20 Blast campaign against Derbyshire at 14:30. You can hear every ball of every county match live on the BBC Sport website.

Mendis - fuelled by surviving a dropped catch in the last over - punches a Broad delivery down the ground that beats the chasing Thompson. The sub-fielder has more success later in the over with a diving stop to take the sting out of a fierce drive and prevent another boundary.

Barring that nick in Finn's over, Mendis has looked solid.

"I don't think it would have carried to Cook. He's right to go for it and he should have caught it. He had time. It never went in the glove and hit him on the wrist."

Oh, Jonny! Finn finds the perfect length and catches the edge of Mendis' bat but the diving Bairstow fails to take it with one glove. That is his first aberration during a match in which he has snaffled everything that has come his way.

It is a much better over from the Middlesex bowler. Far more consistent. 

The floodlights are on.

"Broad's got a much better length in the last few balls. He's running uphill and got into a better rhythm."

We've have a sub fielder change at drinks. The new man plays for my local club. Take a bow Pudsey St Lawrence's Jordan Thompson. Now go and get all Gary Pratt on us.

Broad is back into the attack, replacing Anderson. He almost picks up where Jimmy left off as Mendis outside edges a straight ball high and just over the man at mid on.

The sun has disappeared, the wind is picking up. There could well be a storm coming.

"Steven Finn is not the right bowler for Headingley. I like him a lot, but he bowls back of a length and gets bounce. When he pitches it up, it's floaty. Also, Broad hasn't got his rhythm. Stokes is injured - he would have been on here. At the moment, they're trying to bowl Sri Lanka out with just one bowler - Anderson."

Finn is still struggling for consistency in his fourth over. His first delivery is poor, on Chandimal's pads, and the batsman flicks it away for four. He stays too straight for much of the remainder of the over. Couple of inches to the left and he'd be right on target.

Jimmy Anderson has picked up where he left off...

We now have confirmation - Ben Stokes has jarred his knee and won't bowl today. He is off the field receiving treatment. Mind you, with Anderson in this form and the match in the shape it is there are worse days for England to be a bowler short.

Jimmy continues his assault, jagging a shortish ball back in to Mendis, who gets lucky with a steer that James Vince gets a hand to but can't claim or prevent the ball flying to the rope. It feels a bit harsh to call it a dropped catch.
