Kris Boyd was still waiting to hear from Rangers about his impending move to Birmingham, according to the striker's agent.
Boyd's prolific Ibrox career will come to an end if the Coca-Cola Championship club agree to increase their £3million offer for the 25-year-old.
Rangers confirmed on Tuesday night they were prepared to sell their top scorer, but his agent Mark Donaghy told BBC Sport: "I'm waiting on a call from chief executive Martin Bain to tell me what's happening, but no deal's been agreed yet."
The Clydesdale Bank Premier League giants are thought to need the money selling Boyd would bring in, but the loss of a player who has already hit 20 goals this season will not go down well with the club's fans.
Boyd has been Rangers' top scorer for three consecutive seasons, including the 2005-06 campaign despite having joined them only on January 1.
He has scored 91 goals for the club despite struggling to become a regular starter under Paul Le Guen and current boss Walter Smith.
