The former Wales prop took over from Bernard Jackman last month with his appointment resulting in an improvement on the field. Since twice-capped Jones stepped in, Dragons have won two games, including a rare success against a Welsh Pro14 rival when they beat Ospreys 23-22 in late December.
The Dragons have nine fixtures left to play this campaign starting with next Friday’s return fixture against the undefeated Top 14 outfit Clermont and concluding at Principality Stadium against the Scarlets for Judgement Day VII at the end of April.
“Ceri Jones has done a great job leading the team with the support of our coaching group since he stepped up to the role,” said Dragons Chairman David Buttress.
“Ceri has the full support of everyone at the region and it’s clear the players are reacting positively to his leadership with performances full of heart, character and determination. We said before Christmas that we want to make a permanent appointment as soon as possible, but also that it has to be the right person for the region.
“Whilst the search for the permanent head coach is underway, our upturn in performances since Ceri took over has given us the opportunity to take our time. I’m looking forward to seeing what we can achieve over the final months of the campaign.”
