Knights prop Jacob Saifiti is in hospital with a serious leg injury that could sideline him for more than three months following an alleged altercation with the brother of Kangaroos and NSW captain Boyd Cordner outside a Newcastle hotel in the early hours of Sunday morning.

Police are understood to be investigating the incident involving Saifiti and Central Newcastle footballer Dane Cordner, which occurred outside Hamilton’s Greenroof Hotel.

Another setback: Jacob Saifiti fell awkwardly after the alleged punch.

Saifiti was knocked cold by a punch during the incident and suffered a suspected fractured lower leg after falling awkwardly.

He was taken to hospital and was facing surgery that will determine how long he will be sidelined.
