Fulham boss Marco Silva is hopeful Aleksandar Mitrovic's injury isn't serious.
The striker was forced off during their 4-1 home defeat to Newcastle.
Silva said: "Let's see, we have to wait more hours and days to see. We had to make changes because we had four other injured players, let's hope they can recover so that we can be stronger next week.
"I don't want to rely just in Mitro, all players not in the squad are important for us and it is up to us to keep working hard to recover them as quickly as we can."
