Youngster returns for Blades clash
Striker Macauley Bonne is in the U's nineteen man squad, after a spell out injured.
It is expected that the teenager will bag a place on the U's bench, as the U's chase the three points that could take them up to twelfth place in League One.
A win for Dunne's side would also keep the Blades below them, with Nigel Clough's men behind the U's only on goal difference coming into the game.
U's: Walker, Cousins, Olufemi, Wilson, Dickson, Okuonghae, Sesay, Eastman, Gilbey, David Wright, Bean, Eastmond, Sanderson, Sears, Massey, Vose, Morrison, Bonne, Ibehre.
