Lee Camp has pulled out of the Northern Ireland squad ahead of Tuesday's World Cup qualifier against Luxembourg.
Camp was on the substitutes' bench for Friday's 2-0 defeat against Russia as Michael O'Neill opted to give Roy Carroll a first competitive start in six years.
Nottingham Forest goalkeeper Camp has now headed home for personal reasons, with Trevor Carson called up as cover.
Meanwhile, Shane Ferguson has been passed fit for the clash with Luxembourg after missing the Moscow match with a groin problem.
The versatile Newcastle man rejoined the squad in Belfast and took part in training on Sunday morning.
O'Neill will continue to monitor the fitness of Manchester United's Jonny Evans before making a decision on his availability.
Defender Evans admitted to feeling pain in his ankle throughout the Russia match, which may concern his club boss Sir Alex Ferguson, but joined his team-mates in their morning workout.
