Dan Shittu has returned to Queens Park Rangers after being handed a contract until the end of the season.
As revealed by skysports.com earlier this month, Rangers were lining up a move to bring Shittu back to Loftus Road
The defender, who made 182 appearances during a five-year spell at Loftus Road between 2001 and 2006, arrives as a free agent following a stint at Millwall.
The Lions were also eager to agree terms with the Nigeria international after handing him a three-month contract following his summer release by Bolton but he has elected to join the Championship leaders.
Neil Warnock feels Shittu will be an excellent addition to his squad and his previous experience with the club will help him settle immediately.
"I just felt that with the injuries Fitz Hall has had this season that we were maybe one body light in the central defensive area," Warnock told the club's official website.
"We've got to look at every avenue for the last 19 games of what could be the most important period in the club's recent history.
"Dan wanted to come here and I wanted to get him, so it was a no-brainer in that respect. Dan knows the club inside-out and can't wait to get started."
