Charlton have signed Sunderland defender Greg Halford on loan until the end of the season, the Barclays Premier League club have announced.
The 23-year-old defender moves to The Valley after making eight league appearances for the Black Cats following his switch to Wearside from Reading last summer.
Pardew told his club's website: "Part of doing business is to make sure you try to do something that's useful for your club.
"Hopefully, we can have similar success with Greg. He's coming here on loan and I think he's got a lot to prove.
