Sky Sports understands that Leeds United have emerged as favourites to sign Stephen Warnock.
West Ham had shown an interest in the former England man, and had held talks with the left-back after Aston Villa told him he could leave.
The 31-year-old has not featured under Paul Lambert and spent time on loan at Bolton earlier this season.
A number of clubs have shown an interest and he looked set for a switch to West Ham - who need cover at left-back.
"Stephen we thought was a go-er, but another club in the Championship made him a more long-term offer which I think he has accepted, so I think he has decided to take that so that," said Hammers boss Sam Allardyce.
Leeds have now moved into pole position due to the fact they could offer Warnock a longer-term deal - which looks to have persuaded him that his future lies at Elland Road.
