Their last two Premier League games have been postponed after a number of players tested positive for coronavirus.
Clubs must play their FA Cup third-round fixtures this weekend or risk forfeiting the tie. The FA have told clubs to play if they have 14 players fit.
Fulham players will be tested again this week.
Fulham have deep cleaned their Motspur Park training ground, with some areas remaining closed in order to reduce the number of people on site. Furthermore, training is being scaled back to a level close to the early stages of Project Restart where players worked in small groups and trained at different times in order to reduce the spread.
The club are continuing their investigation into striker Aleksander Mitrovic after the Serb was revealed to have spent New Year’s Eve with international teammate and Crystal Palace captain, Luka Milivojevic, in a breach of coronavirus restrictions.
A Fulham statement read: “The player is aware of the club’s disappointment and of the standards that are expected of him. The matter will now be dealt with internally.”
