Kilmarnock have bolstered their squad with nine new signings, including former Sheffield United midfielder Callum McFadzean.
Joshua Webb and Jamie Cobain are added to manager Lee Clark’s defensive options, along with loan arrivals Jonathan Burn and Mark Waddington.
Jordan Jones and Martin Smith are midfielders, while goalkeeper Oliver Davies returns for a second loan spell.
Striker Souleymane Coulibaly has also been recruited.
The 21-year-old, a star at the 2011 Under-17 World Cup for Ivory Coast, arrives from Peterborough United, having been on loan at Newport County last season.
McFadzean, the oldest of the signings at 22, has been capped by Scotland at under-21 level and spent four years with the Blades.
Cobain, 19, arrives from Newcastle United, with Webb, 20, released by Reading.
Clark, a former Newcastle player, has picked up Jones, 21, and Smith, 20, from Middlesbrough and Sunderland, respectively.
Of the loan signings, Davies, 21, returns from Swansea City to provide back-up for Jamie MacDonald, with Burn, 20, from Middlesbrough and Waddington, 19, from Stoke City.
Davies did not feature for Killie last term, with a shoulder injury curtailing his stay at Rugby Park.
