Catalan have been dealt a further blow with the news that hooker Ian Henderson could be out for three months with a broken arm.
Henderson, 30, broke a radius against Leeds on Friday and is set for 10-12 weeks on the sidelines.
He was taken to hospital after the game where he underwent surgery, and joins half-back Scott Dureau on the long-term injured list.
Coach Laurent Frayssinous was without eight players for the trip to Headingley through injury or suspension.
The Dragons have lost three out of three so far in Super League this season.
