Burnley defender Andre Bikey could make a welcome return to action.
The Cameroon international has missed the Clarets' last three games following the rib injury he first sustained at Millwall at the start of October.
After a period of recovery he could now return to challenge Michael Duff and Clarke Carlisle for a starting place against Doncaster.
Laws said: "We are hoping he gets through that all right and he is included in the squad, which again will give me food for thought because Andre has been one of our most consistent performers."
Striker Martin Paterson made his first Championship start since September in Saturday's 2-2 draw at Norwich and looks certain to retain his place after scoring a brace against the Canaries.
Doncaster defender Joseph Mills is doubtful with an ankle injury.
Mills, on loan from Southampton, sustained the injury in Saturday's home win over Millwall and did not train on Monday.
Rovers manager Sean O'Driscoll, who has no other new injury or suspension problems, could recall James Chambers or Mustapha Dumbuya to his back four should Mills fail to make it.
Midfielder Martin Woods is still struggling with a groin strain, striker Billy Sharp is several weeks away from a return to action due to a torn hamstring and defender Adam Lockwood is recovering from a fractured toe.
Long-term absentees Simon Gillett and defender George Friend remain sidelined due to knee injuries as Rovers chase back-to-back league wins for the first time this season.
