Skysports.com understands Anthony Gardner is poised to join Championship outfit Birmingham.
The defender is currently out of contract and available as a free agent.
He severed ties with Hull City at the end of last season, having seen out the campaign on loan at Crystal Palace.
The Eagles were keen to take him back to Selhurst Park, but discussions regarding a deal have come to nothing.
Nottingham Forest were also linked with the former England international at one stage, but they too have been unable to reach an agreement.
That has left the door open for Birmingham to make their move for the towering centre-half.
Gardner is understood to be due in the Midlands on Tuesday for a medical, before putting the finishing touches to a deal with the Blues.
Birmingham boss Chris Hughton has been in the market for a centre-half after offloading Roger Johnson to Wolves and seeing speculation mount regarding the future of Scott Dann.
