Sunderland have contacted Leeds United to enquire about the availability of goalkeeper Andy Lonergan, according to a report.
The 34-year-old returned to Elland Road in the summer from Wolverhampton Wanderers after Rob Green left the Yorkshire club.
However, Lonergan remains second choice behind Felix Wiedwald, his last Championship appearance coming in the 4-1 defeat against his former side at Molineux in November.
According to the Sunderland Echo, the Black Cats are desperate to add to their ranks this month in a bid to stave off their relegation worries and are keen on Lonergan.
The report, however, claims that Leeds are not keen to sell and would only consider a deal if a replacement is signed, as well as wanting a fee for the player, who still has 18 months left on his contract.
Lonergan is well known to Chris Coleman's assistant Kit Symons, the goalkeeper establishing himself as number one during the 46-year-old's time in charge of Fulham.
