Griffiths was sacked from the Newcastle Jets by owner Nathan Tinkler, along with fellow players Kew Jaliens, Adrian Madaschi, and Billy Celeski after a player revolt leading up to, and following a 7–0 drubbing at the hands of Adelaide United. David Carney was reportedly also sacked by Tinkler but this was disputed by Carney and he remained with the club, although Stubbins refused to play him. Griffiths was then signed by Wellington Phoenix on a short term contract through to the end of the 2014/15 A-League season but suffered a serious knee injury.
