David Weir has joined Rangers on loan from Everton for the remainder of the season, the Scottish giants announced Tuesday.
Scotland international Weir becomes the first signing of Walter Smith since the Rangers manager rejoined the club for a second spell in charge last week.
Weir 36, was signed by former Everton manager Smith for the English Premiership side in 1999. Smith subsequently revived the former Hearts defender's Scotland career when in charge of the national side, a post he controversially gave-up to rejoin Rangers.
"I have obviously had the pleasure of working with Walter before and I can't wait to team up with him at Ibrox," Weir told the official Rangers website.
"This is a terrific move for me at this stage of my career and I am eager to get started.
"I have lined up against Rangers many times during my time at Falkirk and Hearts and I am very grateful to Walter for giving me the chance to play for such a massive club."
Smith added: "David has served me well at club and international level throughout the years and I know he can do a good job for Rangers. He is an experienced defender and I am sure he will settle here quickly."
Capped 52 times by his country, Weir is considered capable of bolstering a defence which has been heavily criticised this season with Rangers currently 17 points behind Scottish Premier League leaders and arch-rivals Celtic.
Former Rangers captain Richard Gough, who played alongside Weir at Everton, welcomed his former team-mate's move to Ibrox.
"It's definitely a great move by Walter," Gough said. "David is a top man - you couldn't meet a better person.
"I really enjoyed my time at Everton with him. When I first went there I just knew him as a solid player who used to play for Hearts but who maybe lacked a bit of pace. But David was never really in trouble and that's the sign of a good player. He was brave, read the game easily and is a good passer of the ball.
"I played for Rangers at 36 comfortably so I'm sure David will have no problem playing until the end of the season," Gough added.
Weir could team up at the heart of the Rangers defence with fellow new recruit Andy Webster, a Scotland colleague, who on Monday was given the green light by FIFA and the Scottish Football Association to complete his loan move from Wigan.
Webster's move had been blocked by his former club Hearts, who still held the player's registration with the SFA.
There was no such complications in Weir's transfer, with Everton accepting his move to Rangers.
"David had expressed an interest in going out on loan. We knew there were clubs in England interested as well as Rangers," said Everton boss David Moyes.
"But when David made it clear he wanted to join Rangers we did not want to stand in his way. We are sad to see him leave Everton."
