United have strengthened their attacking options ahead of the weekend's clash with Bury by completing the loan signing of Paul Gallagher.
The Leicester City striker will go straight into Danny Wilson's plans for the home double header against Bury and Doncaster Rovers, who visit Bramall Lane on Tuesday.
The Blades and Leicester City have agreed a month's loan and Gallagher, 28, met his new team-mates on Thursday morning.
Gallagher has played just once for Leicester City this season but has accumulated more than 250 Football League appearances.
He began his career with Blackburn Rovers and had loan spells with Stoke City, Preston North End and Plymouth Argyle before signing for the Foxes for an undisclosed fee in 2009. Gallagher also has one full Scottish cap.
