Nottingham Forest's Jack Hobbs is expected to be out for up to a month with a hamstring injury, but fellow defenders Kelvin Wilson and Michael Mancienne are both nearing a return.
Hobbs had to replaced three minutes before half-time in Saturday's thrilling 4-4 draw against Blackpool.
Reds boss Dougie Freedman told BBC East Midlands Today: "Jack will be out for three or four weeks.
"But Kelvin Wilson is back in training, so that is a position we are ok with."
Mancienne has not played this year and is also set to return.
A succession of injuries for Hobbs has meant he has only started 38 league games for Forest since joining the club in July 2013.
