Wigan back Amos Roberts has been ruled out for approximately eight weeks after rupturing his posterior cruciate knee ligament.
Roberts, 29, picked up the injury while scoring his second try in the 54-14 win over Wakefield on Easter Monday.
He was stretchered off the field and sent to hospital where an x-ray cleared the free-scoring full back of a break, but a later scan revealed ligament damage.
Head Coach Michael Maguire said: “Amos has been enjoying his football and has been doing a great job for us, but we’ve got some good people who can come into the team.
“I know Amos will work extra hard to get back to full fitness as soon as possible.”
Wigan have also confirmed that Thomas Leuluai picked up a bruised foot in the game against Wakefield, an injury that is being monitored as the week progresses, whilst George Carmont and Cameron Phelps could return for the Warriors in this weekend’s game at Salford.
