While they fight to stay in Division One, the race to replace one of them in the top flight is coming along nicely.
Division Two leaders Worcestershire had looked on dodgy ground against fellow promotion hopefuls Surrey before a maiden first-class century from Jack Shantry (pictured) took his side's lead to over 200 runs.
But a man who knows the New Road ground well is former Pears captain Vikram Solanki, who will be out to bat as his side need another 187 runs with nine wickets in hand.
This match could go a long way to determining who will be coming up. I guess they'll want the world to know...
But don't think we'll just be focusing on events at Trent Bridge.
The battle to avoid relegation from Division One is heating up, with second-from-bottom Lancashire grateful for Ashwell Prince's half century against Sussex yesterday which has brought them back into the match.
The Red Rose, drawing motivation from their fierce rivals edging towards the title, resume 89 ahead with six wickets left, while in the other battle of the strugglers Middlesex need another 352 runs to beat Durham, with nine wickets still to tumble.
Will Yorkshire have enough to skittle out the final Notts wickets before the close of play? And will they be deserved champions?

BBC Radio Nottingham at Trent Bridge
"Day four looks like being cooler and cloudier as Yorkshire look to pick up the five wickets they need to secure the Division One title.
"Nottinghamshire will have other ideas though, beginning on 149-5 in their second innings, with an in-form James Taylor unbeaten on 59 and Chris Read, who made 81 not out in the first innings, still to come.
"The home side will be looking to extend the contest for as long as possible but they are still 180 runs away from making Yorkshire bat again.
"It is safe to say the travelling support will again be huge - and the champagne has already been put on ice."
In the absence of suspended captain Andrew Gale, Joe Root is captaining Yorkshire at Trent Bridge.
Speaking at the end of the third day's play, England batsman Root told BBC Look North: "It was a good day.
"We set out at the start of the day saying if we can get 10 wickets, we'd have had an unbelievable day. To get 11 was fantastic.
"We know there's a lot of hard work to go. It's a very unresponsive pitch and to get to the position we are now is testament to how well the guys have performed."
The main talking point will, of course, be whether Yorkshire can wrap up their first Championship title since 2001 with victory against Nottinghamshire at Trent Bridge.
The White Rose, helped by the stunning bowling form of Ryan Sidebottom, Jack Brooks and Adil Rashid, need just five more wickets to wrap up an innings win - with Notts still trailing by 180.
Notts will be hoping their tail can keep on wagging for the whole of Friday, as they look to fend off Warwickshire and hold on to second place in the Division One table.
Good morning and welcome to our live text coverage of the final day of this round of County Championship matches.
Phil Shepka will be your guide for the morning session.
The weather is set fair for most of the country, so let's hope we see some excellent cricket in the autumn sun.
