Skysports.com understands Derby County defender Jordan Stewart is in talks with Sheffield United.
Stewart moved to Pride Park in 2008 from Watford but has since fallen out of favour under new Rams boss Nigel Clough.
Although a regular last season the 27-year-old has struggled for playing time this term and is ready to seek pastures new.
Sheffield boss Kevin Blackwell is keen to bolster his defensive options and has earmarked Stewart as a potential signing.
The Blades will look to push through a deal before the close of the transfer window at 5pm Tuesday.
