Simon Moore 6: Had little chance with Gary Madine's first-half goal.
Enda Stevens 6: Usual display, never stopped running down the Blades flank.
Jack O'Connell 7: Came close to grabbing an equaliser in second half, but headed just wide.
Richard Stearman 6: Took a nasty whack from Gary Madine, and was involved in a battle all afternoon.
Cameron Carter-Vickers 5: Struggled early on against a pacy Bolton attack, and was substituted after half an hour.
Chris Basham 7: Always puts a shift in, and was once again one of United's best performers.
John Fleck 7: Booked for a crunching tackle, but brought a calmness to United's midfield after three-game ban.
Mark Duffy 7: Looked most likely to create a spark for the hosts, but Bolton did well to close the midfielder down.
John Lundstram 6: Produced one stunning block to deny Karl Henry's goal-bound shot.
Billy Sharp 6: Quiet day for the United captain and not surprised to see him replaced by Clayton Donaldson.
Leon Clarke 7: Had United's best chances, but it wasn't the big striker's day.
George Baldock (Carter-Vickers, 31) 7: Surprised the wing-back was dropped, but was impressive when he came on.
Samir Carruthers (Stearman, 79) 6: Late chance in stoppage time, but went just wide.
Clayton Donaldson (Sharp, 61) 6: Never really got into the game, sliced one decent chance wide.
