Swansea's Lukasz Fabianski has dismissed rumours of a move to Roma insisting he is happy in the Premier League.
Head coach Kenny Jackett has not given up hope of keeping Bakary Sako at Wolves beyond the end of the season.
Rigg joined the Barclays Premier League strugglers from Manchester City last season to renew his partnership with then Rangers boss Mark Hughes.
But following Harry Redknapp's appointment as Hughes' successor last month the club have opted for a further change.
They confirmed Rigg's departure in a brief statement on their website that said: "Queens Park Rangers Football Club can confirm that it has been agreed that Mike Rigg will leave his position at Loftus Road."
