Peterborough have agreed a deal to sign Birmingham defender Krystian Pearce on loan.
Pearce is set to join the Championship new boys on a season-long loan after being allowed to leave by Birmingham.
The 19-year-old spent last season on a similar deal at Scunthorpe and impressed at Glanford Park.
Posh boss Darren Ferguson has been searching for a defender since Chris Westwood's move to Wycombe and Pearce will help fill the void which was left by his departure.
Pearce was included in the squad to face Aston Villa in Saturday's pre-season friendly at London Road.
