Fabri is set to start for Fulham against Crystal Palace today.
Sergio Rico, who arrived from Sevilla on loan on deadline day, was expected to be the club's first-choice keeper, but the 24-year-old, who has been a regular in La Liga, will have to settle for a place on the sidelines having trained just once with his new team.
The Daily Mail says Rico speaks little English which poses a major problem for manager Slavisa Jokanovic with regard to communication.
The future of Marcus Bettinelli, who was expecting to be first choice this season after playing a key role in last season's promotion, is now in doubt.
Bettinelli is on England manager Gareth Southgate's radar, but a call-up depends on him playing regularly.
