Leeds United winger Ryan Hall has joined the Blades on a month's loan.
The 25-year-old is expected to go straight into David Weir's squad for Saturday's home encounter with Preston North End.
"Ryan is a good attacking option to add to the squad, he offers us something a little different to what we already have at Bramall Lane," said Blades chief David Weir.
Hall came through the ranks at Crystal Palace and had numerous loan spells before making his name with Southend United. He proved to be an instant hit in Essex and in his first season racked up the most assists of any player in League Two.
In Hall's second season at Southend he scored 14 goals and notched 25 assists for them during the course of the 2011/12 season.
In October 2012 after much speculation, Hall joined Leeds on-loan with the view to a permanent move in January, which he duly completed.
During his time at Elland Road, the attacker has mostly been on the periphery of the squad and hasn't featured under Brian McDermott this term.
Hall is the second arrival at Bramall Lane this week after the club completed the signature of Marlon King on Wednesday.
