Robert Campbell is leaving Killie on loan for a second time
The 20-year-old forward will remain with the Third Division outfit until the January transfer window.
He was on loan to Dundee in Division One last season.
Campbell played the opening half of the 0-0 draw with Scottish Premier League outfit Kilmarnock at Sons' Strathclyde Homes Stadium.
There was no place in the Killie side for Scotland striker Steven Naismith, who has been the subject of summer transfer bids from Rangers.
Campbell, who has made just two substitute appearances for Killie, played 19 times for Dundee last season without scoring.
