Nigel Clough has bolstered his attacking options with the signing of Blackpool striker Steven Davies.
The 27-year-old, who is eligible to feature against Fleetwood Town, joins the Blades on loan for the remainder of the season.
Davies previously worked with Clough and his staff during their time together at Derby County and this season, despite Blackpool's struggles in the Championship, the striker has netted six goals in 18 appearances in all competitions.
On the acquisition, Clough remarked: "We know Steven's talents very well from our time together at Derby. He is a proven Championship striker who will provide a contrast to what we already have in that area. It has been no secret that we've been trying to get in a striker and we hope he will provide firepower for the run in."
The Liverpool-born marksman started his career with Tranmere Rovers, before moving to Pride Park in August 2008, with the Rams ordered to pay a hefty compensation fee for Davies's services at the time.
At Derby, he scored 21 league goals in 83 appearances, before moving to Bristol City for a fee around £750,000 in August 2012. But after one season at Ashton Gate, he was on the move again, this time to Bloomfield Road to join the Tangerines, who were managed by Ian Holloway at the time.
