Wolverhampton Wanderers forward Nouha Dicko has returned from international duty with Mali earlier than expected because of a hamstring problem.
The 22-year-old has not played for the Championship club since 25 October.
Wolves boss Kenny Jackett told the club website: "Dicko felt his hamstring in training and has come back.
"The good thing is there's no damage, but it seems there's an underlying problem. As for this Saturday, I think he's extremely doubtful."
Dicko has scored 17 goals in 33 appearances since January for Jackett's side, who host Nottingham Forest at Molineux on Saturday.
Mali, who are currently second in African Cup of Nations qualifying Group B, face Algeria in their final group game on Wednesday.
