Kilmarnock have re-signed French centre-back Mohamadou Sissoko on loan from Udinese.
Sissoko has signed another loan deal after making 31 appearances for the Scottish Premier League club last season.
Killie manager Kenny Shiels has been seeking a centre-half since Ryan O'Leary was ruled out for the majority of the season with a damaged cruciate ligament.
The 23-year-old was one of Shiels' main targets this summer and comes in days after the Rugby Park manager released full-back Tim Clancy to Motherwell in a bid to free up wages.
Kilmarnock made another signing with the capture of 18-year-old midfielder Jude Winchester from Linfield.
The Northern Ireland U18 international has been on trial with the Ayrshire club and comes in from the Belfast club's youth team.
