Derby have signed Charlton striker Luke Varney, while Jay McEveley has gone in the opposite direction.
As revealed by skysports.com earlier this week, Charlton had lined up a loan deal for McEveley and were prepared to offer Varney as a sweetener in any move.
Varney has initially joined on loan with the move set to become permanent when the transfer window reopens in January.
Rams boss Paul Jewell is a big admirer of Varney and believes he will prove to be a valuable addition to his squad.
"Luke is a player who I have admired for some time and whose progress I have been monitoring," Jewell told the club's official website.
"He has great pace and ability and I am delighted to bring him to Derby County."
Scottish defender McEveley, who has only recently returned from a loan spell from Preston, has agreed a three-month loan deal at The Valley.
Charlton caretaker boss Phil Parkinson was delighted to bring in McEveley as he looks to solve the problematic left-back spot.
"I'm also delighted to bring Jay in. Despite his young age, he has got a lot of experience, both in the Premier League and the Championship.
"He's a big, strong, athletic full-back, who will give us much-needed consistency in that area."
