Derby County have signed defender Efe Ambrose on a short-term deal until the end of the season, subject to international clearance.
The 30-year-old joins as a free agent, having triggered a release clause to leave Scottish Premiership side Hibernian last month.
Ambrose, who has been training with Frank Lampard's side this week, was part of the Hibs team that won the Scottish Championship title two seasons ago.
He previously spent five seasons at Celtic, where he made 168 appearances, winning four Scottish Premiership titles and featuring in the Champions League.
Speaking about the signing, Lampard told Derby's official website: "We've had the chance to take a look at Efe over the last few days and likewise he has been able to see how we work and want to play.
"Efe is an experienced central defender and he gives us another option in that particular area. We're pleased to welcome him on board for the rest of the season."
Derby are currently 7th in the Championship table, level on points with Middlesbrough in sixth, and nine behind the automatic promotion places.
