Blackburn Rovers are hoping to persuade Birmingham midfielder David Dunn to move to Ewood Park, despite the midfielder already agreeing a deal with Bolton.
Dunn, 27, passed a medical at Bolton and looked set to move to The Reebok in a £2.2m switch.
But Blackburn have now been given permission to talk to Dunn, about a return to the club he left in 2003.
Blackburn chairman John Williams said: “We’ve got permission to speak to David Dunn and we are now going through the normal procedures regarding a medical and personal terms.”
Dunn previously made 169 appearances for Rovers, helping the club win the Worthington Cup in 2002.
He left Blackburn after a bitter fall-out with then manager Graeme Souness.
Injuries have restricted Dunn’s appearances in three-and-a-half seasons at St Andrews.
Birmingham manager Steve Bruce admitted that a move was in the player’s interests.
“It is a total package of £2.2m but a lot of that is obviously based on appearances,” said Bruce.
“We feel a change of environment, a change of scenery will benefit him and we wish him well.
“Dunny has only started 27 times for us which is a shame for our club and a shame for Dunny because when I signed him I paid a lot of money for a quality player.
“It is a crying shame with the amount of talent Dunny has got that we have never seen the best of him at Birmingham. It is one of my biggest regrets as Birmingham manager.”
