The Dragons have parted company with their head coach and former Leinster and Ireland international Bernard Jackman 18 months into his three-year deal at the Welsh side.
Jackman, 42, arrived at Rodney Parade in 2017 but has overseen just three wins from 10 outings in the Guinness Pro 14 this season and Dragons have won just one of their three European Challenge Cup games.
Forwards coach Ceri Jones will take control on an interim basis ahead of the weekend Challenge Cup match against Clermont Auvergne in France.
Dragons chairman David Buttress said: “I would like to place on record our gratitude to Bernard Jackman for his dedication and hard work in his role as head coach.
“Although this has been a difficult decision, we believe it provides us with the best opportunity to create future success on the pitch.”
Jackman said: “I would like to thank the WRU and the board for the opportunity at the Dragons and I believe that there is a bright future for the region.”
