Kilmarnock have confirmed that assistant manager Sandy Clark has left the Rugby Park club in order to pursue other opportunities.
Clark was No 2 to boss Allan Johnston at Queen of the South before the pair made the switch to Ayrshire last summer.
A Kilmarnock spokesman said: "We would like to thank Sandy for his diligence and professionalism over season 2013/14. In testing circumstances, his wealth of experience was an important factor in the club pulling clear of the relegation play-off. We wish him every success in the future."
