Real Zaragoza continue to ring the changes - with one in and three out in their latest dealings - as they attempt to jump out of the La Liga drop zone.
The player brought in is striker Adrian Colunga, who has joined on loan from Segunda Division Recreativo Huelva until the end of the season.
The 25-year-old becomes the Spanish strugglers' fourth signing of the January transfer window, following in the footsteps of Jiri Jarosik, Humberto Suazo and Eliseu.
In turn, Zaragoza's Brazilian striker Braulio has moved to Recre on a similar deal, while the club, who are currently rooted in the bottom two of the Spanish top flight, have also said their farewells to veteran defender Roberto Ayala.
The 36-year-old former Argentina international has reached an agreement to rescind his contract after joining Zaragoza in 2007 and playing 81 competitive games for the side.
In a further change, Zaragoza have also agreed to let Cameroon winger Franck Songo'o join Real Sociedad on loan for the remainder of the season.
