Forest keeper Lee Camp's future at the City Ground has come under scrutiny in recent weeks with Reading reportedly interested in the Northern Ireland international, whose contract is set to expire at the end of the season.
Green has been out of favour at QPR and newspaper reports on Thursday morning were sounding him out as Camp's replacement.
However, the 32-year-old told talkSPORT: "This is the first I've heard about Nottingham Forest. I don't know anything about it."
Green has made just nine starts since his summer switch to QPR from West Ham.
