The Honest Men are keen to add more experience to their ranks ahead of the new season.
Ayr United are in pole position to land experienced left back Liam Dick.
The Honest Men head the queue for the 29-year-old, who has just left Raith Rovers having played more than 150 games during his stint in Kirkcaldy.
Dick, who has also enjoyed spells at Falkirk, Dumbarton and Stranraer, has confirmed he is set for his “next chapter” after deciding to leave Barry Robson’s side following four years in Fife.
Scott Brown is a keen admirer of the full back and would like to strengthen the position with another player who has been over Championship course and distance.
It follows this week’s capture of former Partick Thistle goalkeeper David Mitchell, with the 35-year-old swapping Maryhill for Somerset Park.
United remain in talks with their out of contract players and could face competition from the top flight to retain the services of Connor McLennan, with the midfielder mulling over his future.
