Sheffield United boss Kevin Blackwell may be forced into the loan market following injury to striker Henri Camara.
Blackwell said: "We don't know the severity of Henri's groin injury, but as soon as it went (at Doncaster) he came off.
"It leaves us threadbare in terms of strikers and I'm going to have to consider trying to get a loan in for Wednesday night.
"Certainly no Championship club is likely to help us out, so it seems likely that we will probably focus our efforts on young Premier League players.
"If we don't succeed though, whoever comes in will do a good job because our strength is in our resilience - our players, loans or not, all want to do their best for Sheffield United."
