Fulham defender Tosin Adarabioyo could be sidelined for up two months after undergoing groin surgery.
The former Manchester City centre-back, who saw a move to Monaco fall through last month, has only featured as an 89th-minute substitute against Arsenal this campaign and Whites boss Marco Silva said the 25-year-old has been dealing with the problem for some time.
“It was something he was nursing for the last few games of last season,” Silva said.
“So he has he had a small surgery and he is going to be out for for six to seven weeks.”
Midfielder Sasa Lucic will also miss Saturday’s game at Crystal Palace as he also recovers from a groin problem that has kept him out for over a month but Silva said he could feature in next week’s Carabao Cup match against Norwich.
Winger Adama Trarore is also unavailable due to a hamstring injury.
“Sasa should back against Norwich, or the Chelsea game, It was something in his groin that he felt in the game at Arsenal,” Silva said.
“Adama has a muscle injury, these things can happen when a player doesn’t have a full pre-season.
“Almost all of his pre-season he was training alone with a private physio but it is completely different to when you are in with a team doing a proper pre-season.
“We had a behind-closed doors game during the international break and his felt something in his hamstring.”
Antonee Robinson has been cleared to return after missing last week’s 1-0 win over Luton.
“We have another session tomorrow, but Robinson has been training with the team since the beginning of the week and he will probably be ready,” Silva said.
