Scott Parker is hopeful of having winger Ademola Lookman back for Sunday's Premier League meeting with Arsenal at the Emirates Stadium.
The Cottagers have lost their last four league matches and are six points from safety, having also played a game more than 17th-placed Newcastle United.
Lookman missed the most recent of those defeats, a late 1-0 reverse at the hands of Wolverhampton Wanderers, with a hamstring injury.
However, the RB Leipzig loanee may be back involved this weekend, which would allow Parker to alter his formation slightly should he wish.
If Lookman is not deemed fit enough to start, Ruben Loftus-Cheek and Bobby Decordova-Reid will likely get the nod just behind Aleksandar Mitrovic.
Mitrovic has overtaken Ivan Cavaleiro and Josh Maja in the pecking order, but the Serbian has lost 14 and drawn two of his previous 16 London derbies in the Premier League.
Parker also has to decide between Mario Lemina and Andre-Frank Zambo Anguissa alongside Harrison Reed in central midfield, with the former getting the nod against Wolves.
Tom Cairney and Marek Rodak are Fulham's only other known injury and suspension concerns.
How Fulham could line up against Fulham: Areola; Aina, Andersen, Adarabioyo; Tete, Lemina, Reed, Robinson; Cordova-Reid, Loftus-Cheek; Mitrovic
