Panthers winger Dallin Watene-Zelezniak will be sidelined for six weeks after scans revealed he suffered a broken jaw.
The 22-year-old will today undergo a procedure to have a fracture splint inserted on his teeth.
The setback sees Watene-Zelezniak join Sam McKendry and Tim Browne as casualties emerging from last Saturday's NRL and ISP fixtures.
Watene-Zelezniak's replacement on the right wing will be revealed when the Panthers line up against the Bulldogs at ANZ Stadium on Friday.
