Ryan Sidebottom is still struggling to find his lines at Lord's The 38-year-old is sending plenty down the leg side.

Nick Gubbins meanwhile is still looking very composed with a third boundary off Jack Brooks' previous over - another super cover drive.

Jonathan Trott is now at the crease for Warwickshire after the fourth-ball dismissal of Ian Westwood.

Down at the Ageas Bowl, where Hampshire realistically need to win to stay up, they've moved to 14-0 with Jimmy Adams and Will Smith batting.

Middlesex opener Nick Gubbins looks in some touch. The left-hander clips Ryan Sidebottom for the easiest of fours off his hips and goes past 1,200 runs for the season in the process.

Sidebottom hasn't quite found his lines yet.

No alarms for Somerset at Taunton so far. The bespectacled Marcus Trescothick and his junior partner Tom Abell at the crease.

Jack Brooks finds some early swing, with one beating Nick Gubbins and through wicketkeeper Andy Hodd down to the boundary for byes.

Gubbins then gets off the mark with a beautiful cover drive for four. I wouldn't fancy batting in these conditions - it's murky, cool and swingy - if that's a word?!

Ryan Sidebottom gets proceedings under way at a very empty Lord's, bowling to Sam Robson. Come on folks - this could be the Championship decider!

Yorkshire coach Jason Gillespie has described the decisive final week of the County Championship season as a "great advert" for county cricket.

I couldn't have put it better myself Jason! The players are out at a very gloomy Lord's and are beginning to make their way into the middle elsewhere. We're all set to go...

I'm afraid Division Two can't quite live up to the excitement of its big brother Division One this week.

Essex are already champions and have sealed the one promotion spot, while winless Derbyshire are guaranteed to finish bottom.

Maybe someone will beat Brian Lara's 501* or take 10 wickets in 10 balls to liven things up?! 

The relegation battle is also a three-way split between Hampshire, Warwickshire and Lancashire.

Hampshire are in the greatest danger of going down, with Lancashire needing 11 points to be certain of staying up and Warwickshire requiring 17.

If Warwickshire lose at Edgbaston, a Hampshire victory against Durham would keep them up - no matter how many points they take.

There are too many permutations to go into - but I'll try and keep you best updated as the matches unfold!

Or, for the mathematicians among you - the table is here.

Nottinghamshire: Mullaney, Libby, Moores, Lumb, Patel, B Root, Read, Hutton, Carter, Ball, Tahir

Division One:

Hampshire v Durham - toss uncontested, Durham bowl

Middlesex v Yorkshire - toss uncontested, Yorkshire bowl

Somerset v Notts - Somerset won the toss and elected to bat

Warwickshire v Lancashire - toss uncontested, Lancashire bowl

Division Two:

Gloucestershire v Sussex - start delayed

Kent v Essex - start delayed

Leicestershire v Glamorgan - toss uncontested, Glamorgan bowl

Worcestershire v Derbyshire - toss uncontested, Derbyshire bowl

Yorkshire, are without England pair Jonny Bairstow and Joe Root. Middlesex are unchanged. Both sides look strong.

The weather for London looks dry, but dull. It definitely looks a good one to bowl. 

The good news is the rest of the week looks dry too.

Straight to news from the middle at Lord's - the toss has been uncontested and Yorkshire are bowling first.

In Taunton, Somerset have won the toss and elected to bat against Nottinghamshire.

So, how's it all going to unfold over the next few days. I have no idea! But here's what could happen...

Quite simply, if Middlesex beat Yorkshire, Middlesex are champions for the first time in 23 years.

If Yorkshire win at Lord's, they will win the title as long as they at least match the number of points Somerset take.

If Middlesex and Yorkshire draw, then Somerset will win the title if they beat already-relegated Nottinghamshire with at least 23 points.

In 2015, as the County Championship entered its final week, Yorkshire's players were already sipping on Yorkshire tea and tucking into their 'Parkin' with the title in the bag.

However, this year things are different. There are new pretenders to the throne.

Middlesex, without a title since 1993, and Somerset, still to be crowned County Champions in their history, want a piece of the glory.

What better than a nice showdown at Lord's and a sprinkling of action from Taunton to decide who takes home the trophy.

Welcome to our live text commentary of the final week.
