Nottingham Forest manager Steve Cotterill says there is no chance of signing new players to help them in their Championship relegation scrap.
Forest are third from bottom and morale at the City Ground dipped even further following Tuesday's FA Cup third-round thumping against Leicester City.
Cotterill said: "If you can't afford to sign players, what's the answer when you have half your back four inured?
"We have to tough it out and try to get players back fit quickly."
Injuries to Wes Morgan and Chris Cohen and a suspension for Luke Chambers meant midfielder Guy Moussi had to play at centre-half against the Foxes, while Marlon Harewood is the only new arrival at the club since the January transfer window opened.
And Cotterill insists there is no hope other new faces will follow, even though he is desperate to freshen things up.
"If there would have been some wriggle-room, I would have done it by now," he added.
A clearly angry Forest boss admitted confidence was at a low ebb following the 4-0 reverse at the King Power Stadium.
Cotterill told BBC Radio Nottingham: "It was a tough evening. It was tough for everyone connected with the club but when you are the manager, you take it a little bit more to heart.
"I'm very disappointed. We know we had to make changes, we know who is missing but it's still very disappointing.
"We started OK and started the second half better but it shouldn't last for five or 10 minutes. And when a goal goes in we don't fancy us getting goal back so we almost write the game off.
"We haven't been scoring so when we don't get our noses in front it's difficult.
"We have had our backsides slapped. It's very painful to everyone at the club."
