Charlton have agreed the signing of Portsmouth defender Linvoy Primus on a season-long loan deal.
The 34-year-old, who started his career at The Valley, has slipped behind Sol Campbell, Sylvain Distin, Noe Pamarot and Younes Kaboul in the pecking order at Pompey despite signing a one-year deal in the summer.
Charlton boss Alan Pardew has been on the hunt for a centre-back since Madjid Bougherra joined Rangers last month.
'We've agreed with Portsmouth that Linvoy Primus will come here,' said Pardew.
'He'll spend the first part of the week training with Portsmouth as he's still carrying a knock, but he'll be with us on Wednesday and I think he'll be a big signing.
'He's an old Charlton player, he's loved by the fans here and his experience and character will add to what we've got.'
Primus could go straight into the Addicks squad which travels to Preston on Saturday.
