The 32 year old moved to Loftus Road on a six-month deal in January after leaving Blackburn, but was not going to be offered a longer-term contract.
"I didn't think there was any point in not telling him early, so he could get fixed up," said QPR boss Neil Warnock.
"I haven't seen him. He's not been training with us, although he'd be quite welcome to."
He was signed by Warnock primarily as cover, and did not start a single game for the Championship leaders.
