In-form striker Ched Evans scored twice as Sheffield United beat Rochdale to make it five wins in a row.
Evans opened the scoring after Dale defender Stephen Jordan failed to head clear from Lecsinel Jean-Francois' ball into the area.
Richard Cresswell made it two when he steered the ball in at the near post following a cross from Jean-Francois.
Evans then scored his eighth goal in five games with a superb 25-yard free-kick to seal the points.
The game was held up for 10 minutes following a clash of heads between Rochdale goalkeeper David Lucas and United's Dean Holden.
Lucas was carried off on a stretcher and taken to hospital suffering from concussion. He was later released and travelled home with the rest of the squad.
VIEWS FROM THE DRESSING ROOM
Sheffield United boss Danny Wilson told BBC Radio Sheffield:
"We've had many encounters like this over this season and I think we gradually got stronger as the game's gone. The first goal is always the important goal for either side.
"We got it [the opening goal] at a good time from our point of view and if you're the away team and you've got a game plan to come to Bramall Lane, it gets undone with the first goal if we can get it and we did today.
"After that we haven't really had any problems defensively, but going forward I thought we got stronger, we got more possession as we went along, second half in particular, so really it's been a good performance all the way through and another clean sheet which always delights us."
Rochdale manager Steve Eyre told BBC Radio Manchester:
"Goals change games and physical strength was the difference between the two teams today.
"We were under some pressure right from the kick off.
"We played and we've passed and we enjoyed spells and we've had chances today but you saw the benefit of having strong men."
