No McGinn for Dumbarton
Dumbarton are without the suspended Paul McGinn against visitors Livingston.
He will be joined on the sidelines by Hugh Murray, who is also absent with a hamstring injury. Callum Thomson, a new loan recruit from St Mirren, is included in the squad as Dumbarton look for a fourth win in a row.
Manager Ian Murray said: "We have flown under the radar in terms of moving up the table and that is fine with me. We face a tough test to keep it going as Livingston are a good side.
"They came back from a goal down to win at our place earlier in the season and we did the same at theirs, so there really is nothing between us."
Livingston will miss midfielder Stefan Scougall after he completed his move to Sheffield United.
However, defender Coll Donaldson is included despite continued interest from Queen's Park Rangers. Andrew Barrowman is struggling with a toe injury but Kyle Jacobs is included after re-joining the club from Kilmarnock this week.
Manager John McGlynn said: "This should be a very interesting game as Dumbarton are flying high just now but we know that a win would take us above them in the table.
"We lost to Morton last week and one of the reasons was that we were not good enough in the final third. If we put that right we can win."
