The Newcastle Knights have confirmed that centre Tautau Moga suffered a season-ending knee injury in the Easter Sunday match against the Dragons.

Scans on Monday have confirmed a complete rupture of his anterior cruciate ligament in his left knee.

Moga will have surgery in the next few weeks and will be out for the rest of the 2018 season.

Following surgery, Moga will need to undergo an intensive rehabilitation program over the next nine to 12 months.
