Cardiff have agreed a fee with Norwich to bring goalkeeper David Marshall to the Bluebirds.
The Scotland international had been expected to leave Carrow Road following the Canaries' relegation to League One with terms now agreed by the two clubs, as revealed by skysports.com earlier on Tuesday.
Cardiff chairman Peter Ridsdale confirmed that a 'six-figure' offer had been accepted with Marshall now due to travel to Wales to undergo a medical and discuss personal terms.
Bluebirds boss Dave Jones is keen to strengthen his squad ahead of the new season after the heartache of missing out on the play-offs by a solitary goal after their end-of-season slump.
Former Celtic goalkeeper Marshall will now battle it out with Peter Enckelman for the right to be the club's No.1 shot-stopper for the new season.
Meanwhile, Ridsdale has admitted he could be forced to listen to offers for highly-rated midfielder Joe Ledley, who is out of contract next summer.
Ledley has turned down the Bluebirds' initial offer of a new deal and, although that proposal remains on the table, the club do not want to run the risk of missing out on a sizeable transfer fee.
Stoke, West Ham and Fulham have all been linked with the Wales international, with Cardiff still entitled to some compensation should he leave next summer due to his age.
"Joe is out of contract during the summer of 2010 and we can not allow ourselves to get into a position where he could walk away from Cardiff City at the end of next season," Ridsdale told the South Wales Echo.
"Our offer is still open for us to sit down for talks on a new contract."
