Newcastle forward Lachlan Fitzgibbon will be out of action for at least four weeks, after suffering ligament damage to his elbow on Saturday.

Fitzgibbon sustained the injury early in Saturday’s loss to the Warriors, although played out the remainder of the game before being sent in for scans.

“Everyone saw Lachy got caught awkwardly diving on a loose ball early in the game on Saturday night,” Head of Physical Performance Balin Cupples told the club’s website.
