Universal defender Angus O’Brien will rejoin the Dragons in the 2022-23 season after four seasons at the Scarlets.
The 27-year-old midfielder has played 41 games since moving to the West Wales region in 2018.
He comes back having twice scored for Scarlets at Rodney Parade On April 23 in their rematch they won the United Rugby Championship.
“I’m excited to be back in Rodney Parade and my home region,” O’Brien said.
“I enjoyed four seasons at Scarlets, it was a great experience for me and I learned a lot that I will be able to bring with me to Dragons.
“I went through the academy system at Dragons, grew up with a lot of players, so re-joining these boys and working with them again is an exciting prospect.”
Dragons boss Dean Ryan said: “He is back with a wealth of experience and will give us another way to play the game.
“Angus is a talented and versatile player who will really add to our competition in a semi-finished T-shirt and a full-back.”
Scarlets general manager for rugby John Daniels said: “Angus has been a valuable member of the team for the last four years and we would like to thank him for all he has done for the Scarlets on and off the field and the commitment and honor he has manifested by wearing a Scarlets T-shirt.
We wish him a good transition to the Dragons.
