McCulloch to join Kilmarnock
The 37-year-old was linked with a post at Rangers – where he has spent the last eight seasons – under their new management team of Mark Warburton and David Weir.
However, McCulloch, who during his 19-year career has played in defence, midfield and attack, has elected to follow former Ibrox team-mates Kris Boyd and Stevie Smith to Rugby Park.
McCulloch – who made his debut in senior football for Motherwell in 1996 – will join Gary Locke’s back room staff while continuing to play in Scottish football’s top flight.
