Skysports.com understands that Leeds United's mystery goalkeeping target is former Blackpool player Paul Rachubka.
Elland Road boss Simon Grayson revealed earlier on Tuesday that a deal had been agreed with an unnamed shot-stopper last week, subject to a medical.
The news came in the wake of Monday's surprise decision to accept a bid from Championship rivals Leicester City for Kasper Schmeichel.
Grayson has said that the Schmeichel deal represents good business for the club, but he is also reshaping his squad in order to challenge for promotion to the Premier League.
And it is understood that Rachubka, who is available on a free transfer, has been identified as one of the men to improve the former top-flight club's squad.
The 30-year-old played just three matches for Blackpool last season, including the FA Cup defeat at Southampton and Premier League losses to Sunderland and Everton, conceding nine goals in the process.
