Raiders prop Paul Vaughan returned against Manly in Round 25.

The St George Illawarra Dragons have signed Raiders forward Paul Vaughan on a three-year contract.

The Gungahlin Bulls junior, who can play throughout the forward-pack, has played 85 NRL games to date with Canberra.

The three-time NSW Country Origin representative made his first-grade debut during the 2013 season before later representing the Italy Azzuri at the World Cup.

"I'm very happy to be joining the Dragons who have such a rich history and looking forward to starting the pre-season alongside my new teammates," Vaughan said.

"The focus now is training hard over the coming months to establish myself within a very strong forward pack and playing my role within the squad."
