Middlesbrough have agreed a loan deal with Celtic for defender Stephen McManus.
The Bhoys stopper has joined the Championship outfit for the remainder of the season.
McManus is Boro's fourth Parkhead raid this month following the arrivals of Willo Flood, Chris Killen and Barry Robson.
Boro boss Gordon Strachan has been searching for defensive reinforcements as they have gone five games without keeping a clean sheet.
The 27-year-old could now make his Boro debut against Bristol City, who shipped in six against Cardiff in midweek, at The Riverside.
