Sky Sports understands Lee Camp has been told he can leave Nottingham Forest on a free transfer this month.
The experienced goalkeeper is out of contract in the summer but new manager Alex McLeish has agreed to allow the former Derby man to leave the City Ground ahead of schedule.
Reading had previously been linked with a bid for the 28-year-old and their interest could firm up now the keeper is available without a fee.
A host of Championship clubs including Hull and Ipswich are also believed to be monitoring the situation.
The Northern Ireland international has vast experience having played more than 300 games at Championship level.
