Bob Harris and David Lilley remain on the sidelines for Queen of the South due to suspension.
Midfielder Paul Burns misses out with a groin problem but Stephen McKenna has survived an injury scare and is included in the squad.
Morton manager Allan Moore: "I have the selection headache that every manager dreams about.
"We are in good form and have everyone available so the guys that have dropped out may just find that they cannot just drop back in. Hopefully that will lead to even better performances as the players know that if their standards drop they will be out of the team.
"As well as playing better we have been dogged recently in terms of gaining points and we will need that attribute in abundance against a good Queen of the South side."
Queen of the South manager Kenny Brannigan: "Paul Burns is a wee tiger and wanted to give it a go but he could end up doing himself more damage so we told him to leave it.
"Morton are strong just now but we are going there to win."
