Chris Wilder admits he's not normally one who has a goalkeeper on the bench.
But he may stick with Ben Hinchliffe as one of his subs for the moment.
This is because Billy Turley still suffers from a shoulder problem, following an operation last summer which forced him to miss the first nine games of this season.
The U's boss said: "If you look at my history, as a manager I've tended not to have a goalkeeper on the bench.
"The amount of times you have to call on one is very small.
“Nine times out of ten, or even more frequently than that, your goalkeeper is fine and never has to come off, and having five outfield players as subs gives you more options.
"But at the moment I'm having to think about Billy's shoulder.
“When we get Billy right and he builds his shoulder muscles up, then I can probably look to do that more."
