Sussex have released both Joe Gatting and Andrew Miller following the end of the 2013 campaign.
The 25-year-old middle-order batsman Gatting has spent five seasons at the south-coast club, playing 130 matches across all formats, while Miller, 26, signed from Warwickshire on a one-year deal in the winter but failed to become a regular.
Sussex’s professional cricket manager Mark Robinson said: “It is always a sad time when we release any player but both are still young and we hope a change of environment will help them fulfil their potential.
“Andy and Joe have been model professionals and we would like to thank them both for their hard work and commitment they have shown during their time here at the club. We wish them both all the best for the future.”
