A number of Championship clubs are exploring a loan for Andy King.
Middlesbrough and Sunderland are the latest teams to register an interest.
King has fallen down Claude Puel's pecking order in recent weeks and Leicester are willing to allow a temporary transfer.
Sheffield United and Bristol City have previously asked about the 29-year-old and now Tony Pulis and Chris Coleman are trying for late moves.
Coleman knows all about King, who has 62 goals in 378 games for Leicester, from their time together with Wales.
