Ross County can move to within two points of the First Division title by defeating visitors Raith Rovers, but will be without suspended striker Colin McMenamin.
Defender David McNamee remains sidelined with a broken wrist as the Dingwall men look to make it 28 consecutive league games without defeat.
Manager Derek Adams said: "All we can do if we win this game is open up a bigger gap, so we will stick to the approach we have done all season and that's to focus only on the game in front of us.
"Raith have given us three hard games this season, so we cannot take anything for granted."
Raith will be without top two strikers Brian Graham and John Baird, who are both suspended.
Otherwise, manager John McGlynn has a fully-fit squad.
McGlynn said: "We need the points just as much as Ross County do and the players will need to show the battling qualities they did to get a draw [against Dundee] at Dens Park last weekend to get something.
"We scored twice at Victoria Park earlier in the season and have given them two really hard games at our place so we can head north with confidence."
