Dumbarton v Falkirk
Dumbarton are without defender Frazer Wright as they bid to bounce back from last weekend's 4-2 defeat at Hibernian with victory over Falkirk.
Wright's absence is the latest injury problem to beset boss Stephen Aitken who is also without Scott Taggart (knee), Jamie Lindsay (groin) and Kevin Cawley (ankle).
Aitken said: "Thankfully I have a couple of other options available. The players coming in will have the chance to keep their place, especially if we don't concede goals as cheaply as we did against Hibs."
Falkirk are without defender Kieran Duffie who has a knee injury with Tom Taiwo a doubt after the knock he picked up in the win over Morton last Saturday.
The Bairns are also looking to bounce back from defeat to Hibs after their 1-0 reversal on Tuesday night.
Boss Peter Houston said: "We played well against Hibs and deserved a draw at least so it was a sore defeat. We need to bounce back quickly by winning at Dumbarton and consolidating our place in the top four.
"It is a ground that we won well at just before last Christmas but lost at a few months later so we know that it can be tough."
