Millwall Football Club is pleased to announce the signing of Jason Shackell on loan from Derby County until the end of the season.
The former Burnley captain will add depth and experience to Neil Harris' squad over the remainder of the 2017/18 campaign.
Shackell led The Clarets to promotion to the Premier League in 2014, an achievement that prompted The Rams to make a move for the centre-back the following summer.
The 34-year-old has made two appearances for Derby in the Carabao Cup this season, but is yet to feature in The Championship.
The 6'3" defender will be available for selection this weekend when Millwall host Rochdale in Saturday's Emirates FA Cup Fourth Round tie and has taken squad number 24.
As part of the agreement, Shackell will not be available when Derby County visit The Den in the Sky Bet Championship next Tuesday night.
