Rangers have confirmed that Birmingham have made an approach for prolific striker Kris Boyd.
Some reports claim Blues boss Alex McLeish, who signed Boyd for Rangers, has already succeeded in a bid for the forward.
A short statement from the Ibrox club this evening read: "Following media speculation, Rangers Football Club can confirm that we have received an enquiry from Birmingham for Kris Boyd."
The brief statement appeared to indicate a willingness to sell Boyd should the Coca-Cola Championship side meet Rangers' valuation.
The Light Blues rejected a £2.5million offer from Cardiff before the season started, but reports claim Birmingham are set to succeed with an offer worth up to £4million.
Boyd has been Rangers' top scorer for three consecutive seasons, including the 2005-06 campaign, despite joining the club on January 1.
The 25-year-old has scored 91 goals for the Ibrox side despite struggling to become a regular starter under Paul Le Guen and Walter Smith.
However, he has enjoyed a lengthy run in the first team this season, especially after quitting the Scotland set-up as he struggled to impress George Burley.
Boyd has netted 20 goals this term from a total of 20 starts and three substitute appearances.
