Wigan Warriors centre Oliver Gildart is to be out for "four to five months" and will miss the start of next season following shoulder surgery.
The 23-year-old dislocated his shoulder during Great Britain Lions' opening tour defeat by Tonga in October.
"It's a blow," said head coach Adrian Lam. "Oliver is a quality player, but injuries are part and parcel of a sport as tough as rugby league,"
"The surgery was a success and we'll support him in his rehabilitation."
