Hull KR winger Ben Crooks has been ruled out until early October with a calf injury.
The 27-year-old, who has scored eight tries in 2020, pulled his calf muscle in training and he faces around six weeks on the sidelines.
Hull KR coach Tony Smith said: “The bad news is it’s probably about six weeks.
“He’s pulled his calf muscle in training, it’s a pretty innocuous injury. He was just doing a normal session and got a little bit of tightness.
“Before he even really got a chance to say anything about it, he strained it and limped off. When we sent him for a scan it turns out he’s got a rather nasty tear in it.
“He’s been in terrific form when he’s been able to get on the park this year and he’s scored a heap of great tries.
“We’ve got another training run left and three able wingers able to fill in. so I’ll make the decision later in the week.”
