GP2 team FMS International have confirmed that they will run Roldan Rodriguez alongside Adrian Valles in the main series this year.
Andy Soucek had previously been announced as Valles's teammate, but parted company with the team after pre-season testing.
FMS, owned by grand prix driver Giancarlo Fisichella, drafted in Rodriguez to replace Belgian Michael Herck for the final GP2 Asia round in Dubai two weeks ago and have decided to keep him on for the summer season.
The 23-year-old Spaniard raced for Piquet Sports in GP2 last season and was runner up in Spanish Formula Three in 2006.
FMS also unveiled their new livery for 2008, featuring a similar colour scheme to that on Fisichella's Force India car.
