Sons at full strength
Dumbarton will welcome back Garry Fleming from a ban when they host leaders Hamilton.
Fleming's return gives manager Ian Murray a full squad to choose from.
The Sons are looking to keep their play-off hopes alive going into the last week and Murray said: "Queen of the South are ahead of us as they were clinical last week and we were not. This has been a good season and it would be fantastic to defeat Hamilton in our final home game."
"There is no pressure on us, however, if Livingston do us a favour it will be great to have something to play for next week."
Hamilton welcome back Jonathan Routledge and James Keatings after injury and Ziggy Gordon is available after a ban as they look to keep control of top spot.
The New Douglas Park men are without the banned Stephen Hendrie and Darian MacKinnon.
Player-manager Alex Neil said: "Strange results can happen at this stage of the season so no one can take anything for granted. Dumbarton have their objectives but we can be confident about winning as we are in good form just now.
"We have to remain focused as there are two games left and we need to win both of them."
