Danny Wilson remains confident of drafting in some goalkeeping cover, after being frustrated by the current international break.
The Blades boss was keen to bring in another goalkeeper following the news that Mark Howard (thigh) looks like missing the next two to three months, but was thwarted, commenting:
"It was hard to get in touch with anyone last week because everyone throughout the Premiership and Championship must have been on holiday."
On recommencing his search for a stopper, the Gaffer added: "Of course it is something we are keen to address because we are light in that area and don't want to get caught short in what is a busy period for us in the weeks ahead."
George Long played in Saturday's 1-1 draw with Oldham, whilst 17-year-old George Willis was on the bench for the first time.
