Kilmarnock boss Lee Clark has signed defender Karleigh Osborne on a two-year contract after he left English League 2 side Plymouth Argyle.
The 28-year-old spent several years with Brentford and can also count Millwall, Bristol City, Colchester United and AFC Wimbledon among his former clubs.
His arrival ahead of Saturday's Scottish Cup tie against Hamilton Accies at Rugby Park follows that of Newcastle loan trio Cal Roberts, Freddie Woodman and Sean Longstaff.
