Steve McNamara and Lee Radford have each named their extended squads for this afternoon’s showdown in the south of France.
The Dragons make two changes having being boosted by a return from injury of key duo David Mead and Benjamin Garcia, but lose influential half back Matty Smith with a fresh injury concern.
Arthur Romano is the other man to make way from the 19 man squad.
Hull make four changes through injury and suspension. An injury to Scott Taylor sees the England international out of the squad alongside the suspended Mickey Paea and Andre Savelio, Jez Litten also makes way.
A major boost for the Black and Whites comes in the form of Jake Connor, who has recovered from a knee injury, and he is joined in the squad by Levy Nzoungou and academy star Jack Brown, who could both make their competitive debuts, as well as Jordan Thompson.
