Danny Ratcliffe will replace Grimshaw if he is unable to take his place in the Hawks’ line up.
Hunslet coach Paul March said: “Workington gave us a fright last year. We were quite comfortable in most games, but they made it difficult for us both times we played them.
“As far as we’re concerned, it’s all about our own performance. If we can improve on our Batley performance, then the result will take care of itself.”
March admitted to being frustrated after losing 12-8 against the Batley Bulldogs, despite Hunslet producing “the best defensive display since I’ve been here”, according to the Hawks’ coach.
Joint coach Gary Charlton said: “It was a good week for us.
“We’ve played some decent rugby and the Gateshead performance was best since we’ve been in charge. We played some great rugby and kept putting Gateshead to the sword.”
Charlton has no injury problems to contend with. On Hunslet, he said: “It was a good hard game last year, and we’re expecting the same again this season.
“We’ve strengthened in a few areas and hopefully we can go down there and do well.”
