Blades boss Danny Wilson made four changes to the side for the midweek Johnstone's Paint Trophy penalty shootout defeat at Coventry, while midfielder Kevin McDonald was not included after returning from suspension.
But McDonald, central defender Collins and forward trio Blackman, Porter and Miller could all be back in the side with Callum McFadzean, Richard Cresswell, Marcus Williams and John Cofie expected to make way.
Goalkeeper Mark Howard and Lecsinel John-Francois are making good progress following their respective long-term thigh and knee injuries, but striker Dave Kitson and defender Tony McMahon both remain sidelined with hamstring strains.
The Blades have drawn and lost their previous two league games and have subsequently slipped to fourth place in the table.
