Sheffield v Halifax preview.
Sheriffe struggling with calf problem
Halifax's Rikki Sheriffe will face a fitness test on a calf problem ahead of the Tetley's Challenge Cup fifth-round clash with Sheffield.
The 29-year-od was hurt in the 56-30 Kingstone Press Championship victory over Barrow last weekend.
He told the Halifax Courier: "I pulled up with a slightly tight calf. I am hoping it won't affect my selection for the Sheffield game but I have a feeling it might."
