Wanderers are plotting a move for Leeds United keeper Andy Lonergan.
Owen Coyle wants experienced competition for Adam Bogdan next season and has drawn up a shortlist of half a dozen possible candidates, headed by the 28-year-old former Preston North End stopper.
Lonergan was first choice at Elland Road and also captained the side for a spell last season, but with Neil Warnock looking to bring in his trusted former charge Paddy Kenny from QPR, he could be made available.
Rangers are delaying the move until they have signed a replacement and have been heavily linked with Birmingham's £5million-rated Ben Foster.
Provided those two deals are sorted quickly, Coyle will start talking with Leeds over a player he has rated since his time in the Championship with Burnley.
Lonergan, who boasts four England Under-21 caps, signed for Leeds last summer after 11 years with his home-town club Preston. He made 38 appearances in league and cup last season as the Yorkshire side just missed out on the play-offs.
Jussi Jaaskelainen is closing in on a move to West Ham, and it is understood he will sign a one-year deal next week, subject to a medical.
The Big Finn quit the Reebok after 15 years to search for regular first-team football and could go straight in as Hammers number one, after chairman David Gold revealed that Robert Green has now left the club.
Meanwhile, Wanderers have been handed a bye in the first round of the newly-branded Capital One Cup.
The competition, the new name for the League Cup which has switched sponsors from Carling, kicks off on August 13, five days before the opening weekend of action in the Championship.
The Whites will begin their campaign in the second round on August 27.
