Gloucestershire have offered new contracts to Chris Taylor and Hamish Marshall in an effort to keep them at the County Ground next season.
In both cases the offers are conditional upon the club being granted planning permission to develop their headquarters, with a final decision due at the end of next month.
Taylor and Marshall will be out of contract by then and free to move elsewhere. But, with Jon Lewis already having signed for Surrey, Gloucestershire are keen to retain their remaining senior professionals.
Chief executive Tom Richardson said: “We very much want both Chris and Hamish to stay. But, with our future finances so dependent on the ground development, we have had to make their offers conditional on planning permission being granted.
“If they choose to move away it will be disappointing. But, in that event, we would make efforts to replace them with players of similar ability and experience.
“While we are looking to continue the development of a new and vibrant young team, we are aware of the need for some very good mentors to offer a balance and will recruit accordingly if necessary.”
Taylor, who will be 35 next month, has passed 1,000 LV=County Championship runs this season and is averaging 64.8 in four-day cricket. He is also the club’s fielding coach.
Marshall, 32, has only 346 Championship runs at an average of 24.71, although he has scored the most runs by a Gloucestershire player in the Friends Life t20 competition with 367.
