Ada and Racchi join Shiels' other recent signing, Gary Harkins, at Killie
Kilmarnock manager Kenny Shiels has added another two players to his squad following the arrival of Gary Harkins from Dundee on Monday.
Cameroonian Patrick Ada, a 26-year-old centre-half or full-back, was released by Crewe in the summer and has agreed a two-year deal.
Also moving to Rugby Park until then is Daniel Racchi, previously of York City, who had been at the club on trial.
Before, the 23-year-old midfielder was at Huddersfield, Bury and Wrexham.
Ada made 42 appearances for Crewe last season and was available on a free transfer, while Racchi fell out of favour at Crewe after joining them in January.
His requested for a move to a new club was granted immediately.
Meanwhile, the club has announced new deals for goalkeepers Cammy Bell and Kyle Letheren and defender Ryan O'Leary.
