QPR and Varney's former club Charlton are interested in signing the 27-year-old, but other clubs are also keen.
"It is getting very close to a deal being done," said boss Nigel Clough.
"It will probably be a season-long loan with a view to a permanent move. There are just a few loose ends to tie up."
Varney, whose contract runs to 2012, is one of Derby`s biggest earners but he spent the majority of last season on loan at Sheffield Wednesday.
Varney joined Derby on a permanent deal in January 2009, a few days before Clough became manager.
