Wales prop Rhodri Jones is leaving the Ospreys to join the Dragons at the end of the United Rugby Championship campaign.
The 30-year-old has started just one game this season and will move east in search of regular game-time.
His exit will bring to a close a six-year stint at the Ospreys during which has seen him switch back from tighthead prop to his preferred position on the other side of the scrum. He has consistently impressed with his setpiece work but Toby Booth's side have fellow Wales internationals Gareth Thomas and Nicky Smith on their books plus Rhys Henry, who can play on both sides of the scrum, while the promising Garyn Phillips is out on loan.
