“I’m really excited to have re-signed with the Dragons, we are a very proud Club, I really enjoy being here and they have been great to me,” said King.
“We have a lot of young talented guys coming through the ranks and a great group of established senior players. I believe the Club has a big future and I want to be a part of it.”
The Dragons have also announced Tyson Frizell has agreed to a two-year contract that will see him join the Club next season until at least the end of 2014.
The versatile Wales international and former Australian Rugby Union Schoolboy is currently contracted to the Cronulla Sharks and will join the Dragons in November.
