Micky Adams is waiting to see how his players recover after their draw at Stevenage.
Rovers slipped into the bottom two despite the point, and Adams admitted there were a few knocks and niggles after the game.
However, there was encouragement for Rob Taylor, who played 60 minutes before withdrawing with cramp in both legs, after a hamstring strain had previously kept him out for three weeks.
Josh Thompson was left at home and will continue to recover with the reserves, while Cole Stockton (hernia) and Matt Hill (Achilles) are still not ready to return.
Luton will check on Lewis Kinsella after the defender came off with cramp against Exeter.
The 20-year-old is expected to be fit so Hatters boss John Still should have an unchanged squad to choose from.
Andy Drury was omitted from the squad altogether on Friday so he will hope to be involved this time while the likes of Ricky Miller, Jayden Stockley, Ryan Hall, Nathan Oduwa and Cameron McGeehan are options for Still should he wish to make changes to his starting line-up.
Elliot Lee, Mark Tyler, Pelly Ruddock Mpanzu, Jake Howells and Scott Griffiths all remain unavailable for Luton, who have slipped out of the play-off places after an untimely run of seven straight defeats.
