Paul Williams is down to the bare bones at centre-back.
Michael Mancienne picked up a knee injury early on against Brentford this weekend and it seemed a serious problem.
Forest caretaker boss Paul Williams spoke to BBC Radio Nottingham after the game about Mancienne’s injury, but could not give any real feedback on the problem.
But he did reveal that fellow defender Jack Hobbs has had surgery on a back problem and was likely to have played his final game of the season for the club.
Williams told the BBC:
“I hope not. He has been excellent for us this season.
“Fingers crossed but until we speak to our medical guys I’m not too sure about the extent of hhis injury.
“No Jack is having a back operation. Jack will struggle to make any games this season.”
This will not come as welcome news to Forest fans, who were left disappointed with the performance of Kelvin Wilson this weekend.
The former Celtic man replaced the injured Mancienne and put in a poor show as Forest were put the sword, losing a winnable game on paper 3-0 to Brentford.
The result means Williams is still waiting for his first win as Forest boss and he is now working on trying to pick up a win with reduced central defensive options.
