Nottingham Forest boss Dougie Freedman says it is "touch and go" whether Henri Lansbury will play again this season after suffering an ankle injury.
Lansbury was taken off on a stretcher in the second half of Forest's FA Cup third-round win over QPR on Saturday.
The 25-year-old has scored 25 goals in 124 appearances for Forest since signing from Arsenal in 2012.
"From the X-ray it's not a break, it's ligament damage," Freedman told BBC Radio Nottingham.
"How much ligament damage? He needs an MRI scan.
"The early signs are a lot better than we first feared but it's still touch and go for the rest of the season."
