Scotland U21 international Ewan Urain has left Athletic Bilbao for Unionistas de Salamanca.
Urain has been sold by Athletic Club to the Primera Federación side, with the deal including a buy-back option and a percentage sell-on clause.
He spent last season on loan at SD Amorebieta, scoring three goals in 20 appearances as they won promotion to the Segunda Division.
Urain played a total of 21 matches for Bilbao Athletic, but never managed a first team appearance for the senior team.
