Sheffield United have signed Sunderland defender Neill Collins on loan until the end of the season.
Collins' chances have been restricted at Sunderland
The 22-year-old has not made a league appearance for the Black Cats this season, spending much of the campaign on loan at Hartlepool.
Blades boss Neil Warnock told the club website: "We have a lot of injuries to defenders, so I'm very pleased to get Neill on loan.
"He played very well against us in the league at Sunderland last season."
