The Bulldogs picked up no new injuries but Harrison is ready to make a number of changes for Sunday’s clash with Hunslet Hawks.
Harrison said: “We were very, very poor, but you’ve got to give credit to Featherstone who were quite excellent on the day.”
He added: “Some of these players are probably quite happy being mid-table and I’m not that sort of bloke. They either come to the party or they leave – it’s as simple as that.
“You don’t become a bad team overnight, but we were our worst enemy, and we were made to pay.”
Hawks’ Adam Sullivan is unavailable after receiving a two-match suspension earlier in the week but Hunslet coach Paul March, who steered his side to a remarkable 18-10 triumph at Widnes last week, is not lacking confidence ahead of Sunday’s match.
March said: “We’re full of confidence now. The key is making sure we don’t get carried away. It’s a tough game again this week.
“Defensively we were strong against Widnes. We defended as a unit. There were times when they did break us, but everybody was scrambling for each other and that was massive for me as a coach.
“We’re going into a big couple of weeks. If we can pick points up over the next two games then we’ll be well on our way, but Batley had a disappointing result last week and they’ll come out all guns blazing.”
March is not expected to play himself as he struggles to overcome a groin injury.
