Director of professional cricket Martyn Moxon admits Yorkshire are in a tricky position with regards to making plans for their playing staff ahead of next season.

The White Rose county have nine players, including four first-team regulars, out of contract at the end of this season, but will struggle to make definite plans until they know if England trio Jonny Bairstow, Tim Bresnan and Joe Root will be awarded ECB central contracts.

Bresnan is the only one of the three who holds a central contract, although Root and Bairstow have increment contracts with the national board.

An official announcement on central contracts is usually made in September.

The Yorkshire players out of contract are Bresnan, Dan Hodgson, Phil Jaques, Jack Leaning, Alex Lees, Adam Lyth, Rich Pyrah, Gurman Randhawa and James Wainman.

Ahead of today's LV= County Championship match against champions Warwickshire at Edgbaston, Moxon confirmed: "We've got nine players whose contracts are up for renewal. Discussions are ongoing really.

"There are a few things which need to be considered, particularly what is happening with Bairstow, Root and Bresnan.

"They are the major issues that we have with regards to central contracts or not. There are a few things hopefully we need to clarify before we can start negotiating with the nine. There are financial implications with the central contracts."

The ECB awards up to 16 central contracts of a 12-month duration, and that wage replaces the player's county salary, although the county retains their registration.

Players who are not considered international regulars can also earn an England increment contract via a points system.

Five points are awarded for a Test appearance and two for a Twenty20 or one-day international appearance, with an increment contract being awarded automatically once the player reaches 20 points during the 12-month contract period.

These increment contracts allow England a greater say in the player's management without the formalities of a central contract.

"It's difficult trying to organise your staff for the following year when you don't know until September who's got a central contract, particularly when you've got three involved, Having one is not too bad, but three... " continued Moxon.

"If you're having to pay for three players or not pay for three, it makes a hell of a difference. If none of them have contracts, it's a big financial hit to us."

As thing stand, Root is a shoo-in for a central contract alongside Bresnan, while Bairstow's chances are dependent on the success he has this summer. England only have 11 players centrally contracted for the 2013 season.

Former Australia Test batsman Jaques, 34, has been playing as a domestic qualified player at Headingley for the last two seasons.

The left-hander, who scored 792 runs from 15 Championship matches last term, has scored 147 from four matches this season.

And he has not ruled out extending his stay with the White Rose into 2014: "Contract wise, we haven't really spoken about next season yet," he said.

"Both sides are currently working out what they want to do, and we''ll see where we are in a few months.

"It's definitely something I'll be looking at. We're still working out as a family where we sit, and Yorkshire are still working out what they want to do. I'm sure we'll get some common ground over the next few months."

Jaques is a qualified Level Three coach with Cricket Australia, the highest level possible Down Under.

He undertook the captain/coach role for his club side Sutherland over the winter as they reached their grand final as well as being the assistant coach for the Big Bash Twenty20 team Sydney Thunder.
