Scans confirmed a small fracture in Campbell-Gillard’s jaw which is unrelated to the injury that sidelined the 25-year for a majority of last season.
He is expected to miss four to 10 weeks, meaning he could return for the club’s pre-seasons trials against South Sydney on February 23 and Parramatta the following week.
Panthers general manager Phil Gould confirmed it was not a recurrence of his previous jaw injury.
“It’s not in the same place as his previous fracture,” Gould posted on Twitter.
“It’s not as serious. He will see (the) surgeon to make sure but we anticipate no surgery required.
“He won’t be chewing his food during the Christmas break. But he will be right for trial matches.”
