Dundee boss Neil McCann has made defender Nathan Ralph his fourth signing of the summer.
The 25-year-old left-back moves to Dens Park from National League side Woking and can count Peterborough United and Yeovil Town among his former clubs.
Ralph joins fellow new boys Elton Ngwatala (Kidderminster Harriers), Kharl Madianga (Lokomotiv GO) and Jack Hamilton (Hearts) at the club.
