The Durham collapse was something rather unexpected at about 15:00 BST.

They were tootling along at 215-3 when the new ball was introduced and handed to Matthew Fisher.

Three Fisher overs later he had 4-4 and had conceded just three runs. Alex Lees was bowled for 106 and Jack Burnham yorked for two.

Fisher and Jordan Thompson then did for the next four batsmen who all got ducks and Durham were soon all out, losing 7-45 in 19 overs.

Yorkshire are chasing 171 to win and there were 34 overs left in the day when their second innings began. There's all of tomorrow as well.

Also the start of Derbyshire's second innings at Trent Bridge.

Luis Reece and Billy Godleman the openers as they start their bid to chase an unlikely 365 to win.

Adam Lyth and Tom Kohler-Cadmore head out for Yorkshire's second innings at Chester-le-Street.

They need 172 to win this one after an impressive display by their bowlers this afternoon.

A tense second session of the day that started with Matt Milnes cutting a swathe through the Essex tail with three wickets in seven balls, dismissing Ryan ten Doeschate for 78 and Sam Cook and Matt Quinn in consecutive deliveries.

Kent grabbed all three bowling points while denying Essex their third with the bat by just two runs.

Not to be outdone, Jamie Porter and Sam Cook opened with blistering spells for the home side and removed Daniel Bell-Drummond for five and Jack Leaning for six respectively.

Last ball before tea, a brilliant catch at second slip by Simon Harmer removed the dangerous Ollie Robinson for 14.

We’re poised for a fascinating final session.

Adam Rossington and Charlie Thurston formed an effective union to delay Warwickshire's apparent victory charge, and effectively split the middle session with the Bears.

Although the visitors remain in peril, this partnership has become a substantial annoyance for Warwickshire.

Half an hour after lunch, it seemed entirely possible that Will Rhodes's team wouldn't need to pad up again to win, after Ricardo Vasconcelos drove Alex Thomson airily to short extra-cover, and Tim Bresnan dislodged Rob Keogh and Saif Zaib in the same over.

Rhodes pressed his own medium-pace into service to help cover the continued absence of Olly Stone, and came closer than anyone to taking the next wicket, having Thurston dropped in the slips and Rossington edging through an inconvenient gap in the cordon.

Alas, in his first game as captain, he must refer complaints about not having enough men in catching positions back to himself.

It's tough at the top...

Another good session for Sussex who need just two more wickets after tea to wrap up victory.

The wickets have been shared around with young off-spinner Jack Carson on his debut taking two and his overall match total to four.

Hampshire need an unlikely 110 more and with Keith Barker still at the crease there is a glimmer of hoe, but in reality Sussex should finish this off tonight.

It's tea at Chester-le-Street after Durham are bowled out for 266 in their second innings.

Their last seven wickets falling for just 45 runs as Matthew Fisher takes 4-54.

Yorkshire will require 172 to win.

There were notable contributions with the bat from Haseeb Hameed (52), Steven Mullaney (48) and Samit Patel (80).

Derbyshire will need 365 to win in their second innings - survival may be the more realistic aim.

In fact a few matches have already taken tea on this third day, while some others are not far away from doing so.

We'll bring you up to date shortly with how things stand in all nine matches.

Kent have lost three early wickets now in their second innings at Chelmsford.

Ollie Robinson departs for 14 to the bowling of Matt Quinn.

The visitors 125 ahead after claiming an 89-run first-innings lead earlier when Essex were dismissed for 298.

Nottinghamshire (324 & 271-8) lead Derbyshire (239) by 356 runs

Samit Patel is playing another wonderful innings for Nottinghamshire and clears the rope for his first six.

He moves onto 77 with Jake Ball on 22 as the hosts' lead over Derbyshire stretches to more than 350 runs.

Could we see a declaration at Trent Bridge?

Middlesex building a handy lead at The Oval with a 50 partnership.

Surrey without two of their bowlers at the moment too with Matt Dunn and Jordan Clark both off the field for various reasons.

It's another wicket for Craig Overton - that's seven in the match - and this time he gets some help from twin brother Jamie who catches Kiran Carlson's loose shot at slip.

This one-sided match continues in the same vein.

It's a question of how long this will go on for.

Leicestershire's declaration meant an early tea at New Road but they're back out to commence Lancashire's second innings.

Keaton Jennings and Alex Davies will hope to bat out this 39-over session to help the Red Rose get back ahead in the game.
