Hull Kingston Rovers’ Mose Masoe is in hospital after suffering a serious spinal injury in Sunday’s pre-season friendly against Wakefield Trinity.
The 30-year-old Samoa international forward had overnight surgery at Leeds General Hospital.
A Rovers statement said: “The club will provide further updates as soon as possible.”
New Zealand-born former St Helens favourite Masoe joined Rovers from St George Illawarra Dragons in 2017.
Second row Weller Hauraki also went off during the game with an ankle injury and is to have a scan.
