Hatem Ben Arfa is set for a January move after finding himself unwanted at Newcastle and Hull, his agent has confirmed.
Lucas Silva is unlikely to join Real Madrid in January with the Spanish giants not planning to make any transfers.
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."
