As revealed by skysports.com earlier this week, Birmingham made an enquiry to land Ranger as they look to solve their striking problems.
Birmingham are short of options in attack, with Nikola Zigic, Marlon King and Cameron Jerome sidelined through injury and Blues boss Chris Hughton was keen to raid former club Newcastle for Ranger.
The Championship outfit, who are thought to be struggling financially, were keen on taking Ranger on a six-month loan.
However, Newcastle have rejected their offer as they will only consider a permanent deal for the 20-year-old this summer.
Ranger, who has also attracted interest from Blackpool, is thought to be surplus to requirements at St James' Park, with the player not figuring in Pardew's plans.
It remains to be seen if Birmingham will come back in for Ranger, with Newcastle hoping to offload the former Southampton youngster before the close of the transfer window.
