Rangers have turned down a second, undisclosed bid from Nottingham Forest for Scotland international Lee Wallace.
The 26-year-old has been strongly linked with a move south of the border and Forest are now attempting to land him.
Sky Sports sources understand that Rangers have now rejected two bids from Billy Davies's side.
Wallace has been with Rangers since 2011 and has two years left on his current deal.
Whilst Forest have been in talks with Rangers over Wallace, we also understand a deal to land David Vaughan from Sunderland - currently on loan at the club - is close.
