Nottingham Forest are waiting to discover the extent of the ankle injury sustained by Dele Adebola against Leicester.
The big striker limped off after just 36 minutes of the 1-0 defeat at the Walkers Stadium on Monday night.
"He has an ankle problem so we will have to wait and see, but losing him and Dexter (Blackstock) in successive weeks is not healthy because of the type of players they are," said boss Billy Davies.
The Scot added: "We worked for two or three days on the way we wanted to play and once Dele went off we had to change that."
