Fulham boss Marco Silva says Rodrigo Muniz has avoided serious injury.
The striker suffered a knee injury last week in defeat to Manchester United.
Silva said: “It's not really, really serious, but it's going to prevent him from being involved in the next few games.
“Injuring the knee, you have to be careful. We assessed him and the feedback that I got from the medical staff is that he's going to be a few games out.
“Of course, the international break is going to help us. Probably after the international break, maybe one or two weeks and he's going to be back.
“It's difficult to give a really clear timeline to you about his situation, but let's talk about three or four weeks for him to be back, let's hope."
