Hull KR are likely to be without Ethan Ryan and Albert Vete for their trip to Castleford on Monday, with both players suffering injury setbacks.
Ryan, who this week signed a two-year contract extension, continues to be hampered by a wrist injury that ended his 2020 season prematurely, while Vete has suffered a fresh issue in his recovery from a hamstring problem that saw him sit out the last game against Warrington.
Hull KR coach Tony Smith said: “Unfortunately, in his rehabilitation of his hamstring Albie’s strained his abductor tendon.
“It’s a bit of a freak injury. He’ll see a consultant tomorrow to get a bit more of a steer on that.
“Ethan Ryan has had a scan on his wrist and he has got some issues still going on with it. It hasn’t healed as well as it needs to.
“He’ll either need some time or an operation. We’re just waiting on some news about that too.”
Smith confirmed the worst-case scenario could see Ryan, who has started the last four matches, sidelined for 14 weeks, meaning he would not play again until mid-August, but Smith is confident the player will come back strongly.
Smith said: “From what I understand, whenever that operation occurs it’s expected he’ll be able to perform at the same levels he has been able to.
“Fingers crossed it won’t be as long or as drastic as it could be.”
