Lewis Tierney has been ruled out for four weeks after suffering a facial fracture.
The Catalans speedster suffered the injury in the club’s pre-season victory over Toulouse Olympique.
He underwent scans which confirmed a fracture, which will keep him out for the opening rounds of the year.
It is an unwanted blow for head coach Steve McNamara, who is already a man down in the backs after the departure of Brayden Wiliame to St George Illawarra.
