Watford have released Australian defender Adam Griffiths after his short-term contract with the club came to an end.
The Hornets snapped up the player in the summer as Adrian Boothroyd moved to add numbers to the squad.
Boothroyd told the club's website: "We always viewed Adam's six-month contract as a trial period.
"He hasn't come up to our expectations of him so he moves on. Adam is a great guy and moves on with our best wishes."
