Former Wales hooker Richard Hibbard will leave Gloucester to see out his career with the Dragons at the end of the season.
Hibbard has become a popular figure at Kingsholm since ending his long stay at Ospreys for a stint in the Premiership three years ago.
The 34-year-old forward, who has made 91 appearances for the Cherry and Whites, will follow team-mate Ross Moriarty in returning to his homeland on a three-year deal.
Hibbard said: "I spoke to Bernard [Dragons head coach Jackman], who shared his plans for the Dragons and the direction he wants to take the team and I really want to be part of that.
"I'm excited by the move back and what Bernard is building at the Dragons. Contributing to that will be my focus to get the team into a good place. Success may not be overnight, but hopefully in any small way that I can help I can speed that process up.
"The Dragons have an extremely skilful squad and a few experienced players will add to that. Ross coming in is exciting addition. He'll galvanize the back row and hopefully I can bring some experience in as well.
"I've experienced being against the Dragons fans in the past and now I'm looking forward to joining and having them support me."
