County Championship live updates: How will Archer, Bethell and India's white-ball stars fare?

Bethell makes 20 off 43. With Zak Crawley batting well in the second innings at Headingley, and Ollie Pope making that hundred in the first innings, that might well be that for his hopes of a second Test recall.

An even 100 and out for Tilak Varma, a laudable effort in his first County Championship innings.

Jacob Bethell has finally reached the crease for Warwickshire. He's digging in, one off 17 so far. 

He goes to stumps 98 not out, needing two runs for a century on County Championship debut. Could be a sleeping pill needed there...

We've had one near-miss today, can Varma do what Kishan couldn't? He is 73* with 15 overs left in the day.

Jacob Bethell, carded at No.5, is in the dugout for Warwickshire meanwhile. They are 84-1 in response to Somerset's 498.

Tilak Varma joins Ishan Kishan in reaching fifty in his maiden County Championship knock, though his has been a more sedate innings. His strike rate is below 40, and he has six fours and a six so far.

It's been a long stint in the field for Warwickshire, but they have Somerset nine down, with Bethell having taken two of them - including fellow England white-ball star Tom Banton.

Notts piled up 487 after Kishan's dismissal, with Dillon Penningtion adding 61 at a run a ball and Liam Patterson-White equalling the Indian's 87.

Now, with ball in hand, Pakistan seamer Mohammad Abbas has struck straight away, former England opener Adam Lyth nicking behind to Kishan.

He's one of a handful of batters to make hundreds in consecutive T20I innings, but Tilak Varma is digging in here. He's 30 off 87 with just four boundaries so far.

It's a moment we've waited for for a long time. Jofra Archer's first ball in first-class cricket in four years.

It's down the leg-side but draws a loud appeal, nothing doing from the umpire. The important thing is, he's back.

No century for Ishan Kishan in his first County Championship innings, but a hugely valuable 87 from 98 balls nonetheless.

Hampshire have lost a couple of early wickets, so Tilak Varma is in at No.4. He's 21, averages 50 with the bat in first-class cricket, and has a frankly absurd set of T20 numbers, both domestically and internationally. 

Sussex, who initially didn't include Archer in their squad graphics for this game, have also now not given him the new ball. It's Gurinder Sandhu trundling in with Ollie Robinson instead.

Gurinder Sandhu finally goes for a gritty 8 off 54. James Coles finishes unbeaten on 148. Well batted both.

Now it's Archer time...

Ishan Kishan has picked up where he left off, quickly converting his overnight 44 into a half-century. With the new ball seen off, he has a chance at a big score.

Sussex, meanwhile, are still nine down. James Coles (137*) is playing a blinder, while Aussie No.11 Gurinder Sandhu has turned into Geoffrey Boycott, facing 34 balls for his two runs so far. Once Durham find a way through, it will be over to Jofra Archer with the new ball.

Sussex end nine down, while Kishan goes to stumps unbeaten on 44 and eyeing up a big score tomorrow. Bethell might have to wait a while yet for his turn, with Somerset losing just three wickets all day. It's a little closer to Tilak Varma time - Essex are eight down overnight. Each bowled some part-time overs, so it wasn't a total day one TFC for any of the four in question.

Jofra Archer falls for an entertaining 31, including three fours and a six. There are 4.3 overs left there, so if a wicket falls now, we might just get an over of Archer before stumps.

Get your popcorn out! Ishan Kishan has raced to 26 at a run a ball, his innings laced with five boundaries so far.

Meanwhile, at Sussex, Ollie Robinson's dismissal has brought Jofra Archer to the crease. Don't expect him to hang around.

Sussex are 255-7, with Jofra Archer next in. With 15 overs left in the day, we'll almost certainly see him at the crease tonight, and perhaps there'll be time for a short burst with the ball as well.

Just under an hour into the final session, Ishan Kishan has arrived at the crease for Notts, who are 231-4. He's four off nine so far.

Notts are three down, Joe Clarke the latest to fall for 31, so Ishan Kishan's maiden County Championship innings is almost upon us.

Somerset were 186-0, Tom Kohler-Cadmore having made a century in partnership with fellow opener Josh Davey (imagine telling the Taunton faithful that would happen at the start of the season!)

But Che Simmons has struck twice in two overs to bring Warwickshire back into the game, and take us two wickets closer to Bethell O'clock.

None of Jofra Archer, Jacob Bethell, Tilak Varma and Ishan Kishan have yet had much to do. Sussex are batting, Warwickshire and Hampshire bowling - Bethell has bowled four overs for 23 - and Kishan is in the dressing room with Notts putting up a strong top-order showing.

There's still been plenty of action elsewhere though. Eddie Jack, on County Championship debut but already an England Lions bowler, has had Jordan Cox, returning from a side strain, out fending off a short ball. Cox was troubled in similar fashion in an England shirt against West Indies last year.

There's a bit of rain around, but the Kookaburra ball has talked decently enough so far. Sussex are three down against Durham, Essex have lost four, and Worcestershire five in Division One. Somerset are the only top tier side as yet unbreached.

Pakistan batter Abdullah Shafique has been denied the chance to make his County Championship debut for Yorkshire against Nottinghamshire due to visa issues.

India white-ball batters Tilak Varma and Ishan Kishan are a couple of star additions to this round, turning out for Hampshire and Nottinghamshire respectively.

Meanwhile, New Zealand's Will O'Rourke is also playing for Yorkshire. 

In action for Warwickshire and Sussex respectively, there will be a close eye on Jacob Bethell and Jofra Archer's performances.

Both players could have roles to play against India this summer, and/or in the Ashes this December.
