Midfielder Olly Lee has left Barnet to join Championship club Birmingham City on loan for the rest of the season.
The 21-year-old has spent the majority of 2013 on trial at St Andrew's, and manager Lee Clark has been impressed with the ability of the former West Ham United trainee.
Clark told the club's official website: "Olly was one of Barnet's standout performers against us in the Capital One Cup earlier this season.
"He's impressed us during his trial and we look forward to seeing him develop."
Lee has made 13 appearances for Barnet.
