Speaking to Radio Sheffield, Scott confirmed he has more injury headaches ahead of Saturdays trip to Northampton.
"Grabbs` back went into spasm and he was struggling and Revs took a couple of whacks on his ankle and just ran out of gas. But Chris Holroyd was outstanding, he was excellent second half so there's no problems putting him in if needed.
"We also think Warro's got a spasm in his thigh which isn't great news," Scott added. "We've got a few knocks starting to pile up over the last few days. Michael Raynes has played with a knock and got through it but we've got Guy Branston back after Saturday and Cressy is doing okay."
