Catalans forward Luke Burgess could be out for the rest of the season with a knee injury.
According to a club statement, there is a strong suspicion he has ruptured anterior cruciate ligaments in his right knee during the win over Leigh, and will see a specialist in the next few days.
Fellow forward Jason Baitieri is also set for an extended spell on the sidelines, after suffering a broken wrist.
He will undergo surgery next week and has been ruled out for between 10 and 12 weeks.
The Dragons are already missing Greg Bird, Jodie Broughton, Justin Horo and Thomas Bosc through injury.
