Peterborough United have signed Celtic defender Josh Thompson on loan until the end of the season, subject to international clearance.
The 20-year-old started 16 Scottish Premier League games for Celtic after signing from Stockport in 2009, but spent last season on loan at Rochdale.
Posh manager Darren Ferguson told the club website: "We had a look at him before he joined Celtic.
"I hope that's the first of a couple of signings before the end of the month."
He added: "We now have four centre-backs and that competition for places is what I was after."
