Turner brings his side to South Yorkshire in fifth place in the league, but has already tasted four defeats on the road this season.
Despite the Millers' poor run of form, Turner told Radio Shropshire that he expects a tough game.
"I thought Rotherham looked a strong team. Some of their summer signings were quite impressive.
"It has surprised me that they've got into a run like this and it'll be a difficult game for us. It could be a very dangerous time to be going and playing them.
"But we have enough about us to go and cause them problems," he added.
We'll have full team news for both sides a little later.
