Sheffield United manager Kevin Blackwell has admitted Reading's Matt Mills is interesting him as he ponders making a swoop for the centre-half to ease his defensive crisis.
With the Blades looking to sharpen up their problems, Mills could fit the bill with Marcel Seip suffering a hamstring injury in their 2-0 FA Cup loss at Bolton on Saturday.
Gary Naysmith has suffered a fresh setback as he recovers from knee surgery and he won't return until mid-March.
The sale of Matthew Kilgallon to Sunderland has left United with an impoverished back-line and, with Blackwell being a long-time admirer of Mills, he could make a move.
Speaking to The Sheffield Star, he said: "He's a player that I thought did very well at Doncaster. We're looking at a few players and Matt Mills is definitely one that I've looked at.
"There are four or five lads we've looked at and it comes down to finances, availability and what position the clubs are in."
