Chesterfield have decided not to offer a new contract to Australian midfielder Jamie McMaster.
The 22-year-old joined the Spireites on a short-term contract from Leeds in March and made eight league appearances in the final weeks of the season.
But boss Roy McFarland said: "Jamie does not feature in our future plans."
McMaster failed to start a League game for Leeds - and as well as a previous loan spell at Chesterfield, was loaned to Coventry, Swindon and Peterborough.
